The sound on the computer turned off what to do. What to do if the sound on the computer disappears

It is difficult to imagine a more ridiculous situation than watching the next issue of Comedy club on a PC without sound. At the same time, this kind of computer malfunction is far from uncommon in user practice. A great example of this is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, the "unauthorized boycott" announced by your PC is definitely an unpleasant surprise for many novice users. Especially when you consider that the problem with sound is quite multifaceted in resolution. However, you, dear reader, are in luck again! Because in just a few minutes you will be able to "untie the tongue" of virtually any Windows operating system. Well, let's not waste precious time - let's turn to the experience of professionals.

Diagnostics of the computer "muteness"

The answer to the question of how to restore sound on a computer needs to be looked for in two ways. The fact is that most often the system "loses its voice" due to software failures. However, the sound may disappear as a result of hardware failure. For example, an integrated audio chip. To understand what exactly is the cause of "silence", you need to resort to a step-by-step plan of action. Only after a thorough practical analysis will you be firmly convinced of whether your audio malfunction is hardware or software. However, let's not talk about the bad - everything should be decided without the intervention of a specialist.

Step number 1. Elementary check

Tell me how to turn on the sound on the computer if the speakers are inoperative or simply not connected? Of course, no way! Exceptionally simple steps can help you avoid mistakes and wasted time.

First of all, you need to check:

Are the speakers connected to the PC and the jack used matches the destination device.
The location of the plug if the speakers are powered from an electrical outlet.
In what position is the volume control. Perhaps it is twisted "to zero".
Is one of the connecting cords damaged?

Often just such "platitudes" push a person to wrong actions. Therefore, be careful. Connect speakers that are known to be working. Perhaps all your fears are in vain!

Step # 2. Discover the "secret" signs

In the event that the sound on the computer has disappeared, pay attention to the speaker-shaped icon located in the system tray. It may be crossed out to indicate deactivation of the playback device. Move the slider up. If everything remains unchanged, proceed to the next solution point.

Step # 3. Windows services

It's no secret that the operating system has incredibly wide functionality. Management and control in the OS is carried out by special services, one of which is responsible for the playback of audio material. It is simply impossible to fully customize sound on a computer without Windows Audio. Therefore, you need to check the current status of this service.

Use the Win + R hotkey combination to bring up the Run menu.
In the window that opens, enter the services.msc command. After confirmation with the "OK" button, you will be redirected to a special section "Services".
Find Windows Audio in the list provided.

For sound to play and audio settings to be correctly recognized by the system, make sure the service is active. That is, the "Status" column contains the "Running" parameter, and the "Startup type" column is set to "Automatic". You can make the necessary changes using the same right mouse button, placing the cursor on the item that requires the corresponding revision.

Step # 4. The driver that can crash

A crossed-out speaker in the tray may also indicate the inability of the special program code that controls the audio chip. In other words, the sound on the computer disappears when the driver becomes inoperable.

Open the start menu.
Then go to the "System" section.
Select "Device Manager" on the left side of the window.

It will not be difficult for you to find the "culprit" of a problematic situation. In the presented list, a non-working device will be marked with an exclamation or prohibitory mark. Update the sound driver using the service disc (software for the motherboard from the kit). In the absence of such, you need to go to the official website of the manufacturer and in the "Support" section download the appropriate modification of your PC software tool. It should be noted that before installing the latest version of the sound driver, you must remove the old device control component.

Standard Windows functionality

When all your attempts at practical actions to answer the question of how to turn on the sound on the computer have not brought fruitful results, it makes sense to use the incredibly convenient option "Troubleshooting". However, this functionality is only available in later versions of the Windows operating system. To run this tool for correcting conflict situations, you need to right-click on the conflicting device (indicated by the system with a special warning sign) and select "Diagnostics and correction" in the context menu. After a few minutes, the OS will notify you of the result of the work performed. It is likely that such a sound setting on a computer will be an effective salvation for a seemingly "dull" situation.

Step # 5. Settings

If you are convinced that the driver is installed correctly, and the service window of the sound device "Properties" displays the current state "Works normally", then the solution to the question "how to turn on sound on the computer" should be sought by the following algorithm of actions:

From the Start menu select Control Panel.
Go to the "Sound" section.
In the window that opens, right-click on the icon of the displayed playback device. Select "Properties" from the context menu.
While on the "General" tab, pay attention to the "Device Application" item below. More precisely, the value in the checkbox. Apply the On option.

In the case when there are several installed playback devices in the mentioned list, one of them should be assigned the "Default" value.

Step # 6. Audio controller

As a rule, in most of the manufactured motherboards the extended sound scheme is implemented. That is, the integrated audio chip can be controlled by a specially installed driver. Let's take a look at an example where the sound setting on a computer is done through the Realtek HD Manager.

Click on the speaker icon (darker in color and slightly larger than the standard Windows volume control).
In the dispatcher's working window that opens, activate the icon in the form of a wrench (lower part of the interface, on the right).
In the case when the sound is not reproduced, it is necessary to change the scheme from one value to another (meaning "Front panel of the AC" 97 "and the item of the same name located just below).

Often it is this change that allows you to use the required audio channel.

Step # 7. Incomprehensible multimedia format

There are frequent cases when audio playback on a computer is impossible due to a missing audio codec. This difficulty can be easily corrected.

Enter K-Lite Codec Pack in the search bar of your browser.
Then select the official source of the product from the list provided.
Download and install the required software.

Typically, this action gives the PC an "omnivorous" multimedia ability. Rest assured that your computer will not be an exception to the rule.

Step number 8. Software incidents

It so happens that after installing a certain software, the sound disappears, and after uninstalling the conflicting program, it reappears. Some media players play a limited number of audio and video formats. This is the only reason why often unlucky users start to panic. Therefore, before installing any program for viewing and playing multimedia content, you should refer to reviews of the product and a review of its tactical and technical capabilities.

Step number 9. Look for the reason in the BIOS

As you know, the BIOS firmware controls and monitors the operation of the entire hardware of a computing device. So installing sound on a computer may turn out to be an impossible mission when the audio functionality is disabled in BIOS for some unknown reason. However, knowing the main rule when working with the basic system: "Do not touch or change unknown values", you will successfully cope with the task.

To check if the audio function is enabled in BIOS, you need to do the following:

Log into your PC's Bios.
Depending on the BSVV version, the location of the sound "switch" may differ. However, the name "AUDIO" and the value "Enabled / Disabled" or "On" are unchanged.
Finding a tab with the Onboard Device Configuration option, or High Definition Audio, is not difficult. The main thing is to understand the seriousness of the enterprise and not make rash changes to the firmware. Since it is fraught ...

Step # 10. System Restore

If, after all the manipulations, the question of how to install sound on the computer remains unresolved, then it would be prudent to use the method presented below.

Go to the start menu.
Enter "restore" in the search box.
After the search section is displayed at the top of the service window, press Enter.
Select the required backup and confirm your choice with the corresponding button.

After rebooting, the system will regain the ability to play sound.

Step 11. Damaged or missing OS files

Sometimes the question of how to make sound on a computer is solved by restoring the lost entries in the system registry. Indeed, very often the user, as a result of erroneous actions (usually in the pursuit of free space on the hard disk), deletes important OS data. Ultimately, the inevitable happens - Windows loses full functionality. However, the unfortunate user does not always have the opportunity to roll back the system to its original state. By the way, the same well-known reason is to blame for everything - saving space on the HDD, that is, there are simply no backups of the OS, since System Restore is deliberately disabled. Nevertheless, even in such a situation, there is a way out.

Press the Win and R keys at the same time.
In the Run menu, type cmd.exe
· In the command window, write sfc / scannow.
Hit Enter.

The damaged data will be restored from the backup storage. It is likely that after restarting the OS, you will hear the sound greeting again.

Step number 12. Viral infection

Malicious code not only steals and destroys user data. A virus program that has infiltrated the operating system environment can also be the reason for the loss of sound on the computer. In order to identify the pest, special software is required. The anti-virus program traditionally used for protection is not quite enough. However, today there are plenty of effective malicious code destroyers on the Internet. Therefore, you should not have much difficulty in the process of finding the necessary software tool.

To ensure that your PC never has sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) to see if more recent drivers have been released.
Connecting devices for audio playback to the system connectors of the PC, it will not be superfluous to understand in more detail the correctness of the connection scheme involved.
Often motherboards have special contact pads that can be closed with special jumpers in order to remap the audio output. Therefore, it is worth referring to the documentation of the motherboard and study the problematic issue in more detail.
If all methods are in vain in terms of your expectations (which is unlikely to happen), seek specialized help.

How do I connect audio on my computer? As you can imagine, this is an incredibly large-scale question. However, today you have learned a lot of information about what needs to be done in order to "talk" your electronic friend, and what you should be wary of while using it. All the best and pleasant sound impressions to you!

The main components of a computer's speaker system are a sound card and an audio output device - speakers (speakers) or headphones. Sound cards of modern computers are implemented in two main categories:

integrated into the computer motherboard (on board);
separate (discrete) sound cards installed inside the computer's system unit.

There are also cheap or very expensive (for professional musicians) external sound cards with a USB connector.

The widespread first option involves unsoldering the audio chip on the motherboard. The more expensive the latter, the better the microcircuit is used in it. But even in this case, the sound quality in on board cards cannot be called high, although it is quite satisfactory for ordinary users. The influence of interference from closely spaced other elements of the system unit sometimes leads to the fact that the audio signal in such cards is distorted. In addition, in the case of a heavy processor load, the sound stutters.

Discrete sound cards have significantly higher audio characteristics. The audio signal processing in them is performed by a specialized sound processor. The delivery set of such a board includes special software that implements various acoustic effects. However, it should be noted that the potentially high sound quality can be leveled out by ordinary speakers or headphones. It is recommended, in particular, to use loudspeakers with wooden enclosures.

Reasons for loss of sound

Sometimes after turning on or while working in the computer, the sound may disappear. Why is there no sound on the computer? The reason for the disappearance or distortion may be a problem in its software or hardware components:

poor contact or failure of speakers or headphones;
incorrect settings of the parameters of audio devices;
damaged drivers;
malfunction of the sound or motherboard (for the on board version) board;
incompatibility with other programs or drivers;
incorrect BIOS settings;
exposure to viruses.

The easiest ways to recover

If the sound just disappeared, you should restart your computer. It happens that sound problems are the result of an accidental failure. If the problem persists, make sure that the speaker speaker switch is on and not in the extreme position. Then visually check the reliability of the connection of the plug of the speakers (or headphones) to the corresponding (green) jack on the computer. Poor contact with the jack can also result in wheezing sound. The performance of the speakers themselves can be checked by connecting to another sound source - a player, a smartphone, another computer.

In the entire line of used versions of the operating system - Windows 7/8/10, as well as in the outdated Windows XP, there is a universal tool - "System Restore". It allows you to return your computer to a usable state. If the sound was normal, for example, a day or a week ago, then you can "roll back the clock" and return to this state. The screenshot below with the image of sequentially opened windows explains the return algorithm ("Control Panel" -> "System" -> "System Protection" -> "Recovery" -> select a restore point -> "Next"). After the computer automatically restarts, the sound should be restored.

Adjusting audio parameters

Inexperienced computer users unknowingly could mute the sound from the taskbar (crossed out speaker or slider brought down). If so, then you need to restore it, as shown in the screenshot (to remove the shutdown, click on the speaker icon).

Then you should go to "Start" -> "Control Panel" -> "Administrative Tools" -> "Services" and make sure that the Windows Audio service is automatically started and running; otherwise, restart it.

To check the settings of the audio parameters, go to "Start" -> "Control Panel" -> "Sound" and make sure there is a green check mark next to the sound device you are using. This means the speakers are working. Otherwise, click on the "Properties" button,

then in a new window open the lower list, select the term "Use this device" and click OK.

Reinstalling Drivers

You can make sure that the sound card is working properly in the Device Manager: "Start" -> "Control Panel" -> "Device Manager". After opening the Sound, Video and Game Controllers list, the presence of the model (Realtek High Definition Audio) and the absence of an alarming yellow exclamation mark next to the line means that everything is in order. If you press the right mouse button on this line, after which - "Properties", then a notification "The device is working normally" will appear in a new window.

Otherwise, you need to update or reinstall the driver. The same need sometimes arises after installing a new partially incompatible device or program. To update, right-click on the Realtek High Definition Audio line and click "Update drivers" in the drop-down list.

The new window offers two ways to find updated, explanatory drivers.

In some cases, the effect is achieved only after removing the existing driver (see the previous screenshot) and a fresh installation from scratch. Windows 7 operating system should automatically install the missing driver upon restart (Plug and Play). If this does not happen, then the required driver can be taken from the disk supplied with the purchase to the discrete sound card or to the motherboard. Finally, as a last resort, the driver can be found and downloaded on the Internet at the site of the card or board manufacturer.

Sound or motherboard malfunctions

These malfunctions are complex and are detected on special equipment of service workshops. However, if you have the same computer in your office or at home (for example, a neighbor's), you can replace the suspect card with a known good one. After checking in this way, the problem can be solved by purchasing a new board.

BIOS settings

It is possible that an inexperienced user, unwittingly, turned off the integrated sound card in the BIOS settings. To enable, you need to restart the computer, enter the settings (by pressing the Del key before the system boots), find the Onboard Devices Configuration section and replace Disabled with Enabled. At the same time, it should be borne in mind that if a discrete sound card is used, this option must be disabled.

The lack of sound may be due to insufficient antivirus protection. In such cases, you need to thoroughly scan the entire computer, possibly with the help of other antiviruses. After detecting and removing viruses, the drivers will most likely need to be reinstalled as described above.

Conclusion

Consistent application of the above recommendations will restore normal sound on your computer. Similar advice can be found in other articles for the search query "Why did my computer sound disappear?"

There can be several reasons for the loss of sound on a laptop, and you can deal with some of them yourself at home. The reasons for the disappearance of sound can be divided into hardware and software.

The hardware rooms include a malfunction of the sound card (repairs in a workshop will be required), malfunction of speakers or headphones, failure of speakers on a laptop, malfunctioning communications (plugs, connectors, cables, etc.).

Software malfunctions include sound settings in the operating system, player, audio manager, driver updates, etc.

Finding the reason for the loss of sound

If the sound on the laptop disappears, what to do at home, what measures to take.

First . Checking sound level in the notification area... At the bottom right of the working window, next to the clock, there is a speaker icon, by clicking on it with the left mouse button, you will see the volume level. Set it to maximum for now. Here you click on the mixer and see the volume controls, also look at the sound on the speaker icon.

How to turn on the sound on a laptop using the keys. The laptop may have a mute button on the keyboard. Maybe the Mute mode is turned on through the keyboard, the desired key is turned on by pressing the Fn + key. Press a couple of times and check the sound. The crossed out speaker should disappear from the screen.

You can adjust the volume (sound) level on a laptop by clicking on the speaker icon in the notification area (tray) and using the "Fn + buttons with the speaker icon" (usually these buttons are the same color as the Fn key). You need to press the Fn button and, without releasing it, press the volume up or down buttons several times.

If the sound on the laptop is quiet, then you need to check all the volume controls, both software and hardware.

Second. Check speakers... To do this, you need to connect an external device (headphones, active speakers, etc.), if sound appears on an external device, you will need to replace the laptop's speakers. Internal speakers on a laptop can fail when working at maximum volume, and for this reason the speakers can begin to wheeze.

If you often used headphones and often inserted a plug into the connector, then the contacts could deteriorate over time. This is especially indicated when, when headphones are connected, the sound reproduction changes (appears, disappears, noise appears, etc.). You need to change the connector in the laptop, you need a specialist.

If the sound card is not working properly, there may be noise, intermittent sound cuts or no sound at all. It is impossible to change the integrated sound card, in which case you can connect an external sound card via USB.

Third . Check Sound Manager(separately installed sound program from the sound card manufacturer). This could be the Realtek High Definition Audio Manager, which is usually located in the notification bar. If it is not there, then you can advise to install the sound driver again, or update it.

Fourth. Check drivers. We go to the device manager and find "Sound devices". If the device is disabled, then enable. If there is a yellow exclamation mark next to the device, then you need to reinstall the driver.

Device Manager

How to enter the device manager: hover the mouse over the "computer" and press the right mouse button, select properties and then "device manager". You can also click "Start" and "Control Panel", in the window that opens, click on the item "System" and there will already be a section "Device Manager".

In the manager, look for your sound card in the sound devices and press the right mouse button, select "update driver". After updating the driver, it is advisable to reboot the system.

If, when updating the driver, the system itself did not find the required driver, then it must be either on a disk to the motherboard with all the drivers, or it can be downloaded from the website of the sound card manufacturer, if the card is built-in, then from the website of the laptop manufacturer.

Sometimes you may need to reinstall the drivers, even if the system says that they do not need updating and everything works fine, but there is no sound.

Fifth. Check Windows "audio" services.

Audio service path: "control panel -> administration -> services -> Windows audio" - this service must be running. If this is not the case, then go to the properties of this service (right-click on the name of the service) and start, as well as set automatic start.

If the audio service is stopped again at the next boot, you can manually add it to autostart.

Sixth. For the built-in sound card, you can check inclusion in BIOS.

We go into the BIOS and find the device item (advanced), find the item with the word audio, for example “High Definition Audio” and set “Enabled” if it was “Disabled”.

You can enter the BIOS when you turn on or restart the laptop, you just need to periodically (every second) press the key, which is indicated for each system separately. You can see the name of such a key at boot time, when the system itself writes that to enter the BIOS, press such and such a key, such a message reads as "Press F2 to Setup". Instead of the F2 key, it can be DEL, F10, F12. Going into the BIOS, find the section "Devices Configuration", or "Integrated Peripherals", or "Onboard Devices Configuration", or "Advanced", and already there you need to find the settings for our sound, the name of the item may contain the word "Audio". The item "High Definition Audio", or another name for your card, should be Enabled.

1) If the sound disappeared after installing programs or updates, then try roll back the system at the time when the sound worked normally. If the sound is restored, then the problem may be in conflict with a new program or updates.

2) If the sound in the laptop stops working and the system writes that device is being used by another application, then you need to look in the tray (next to the clock) which of the applications are running. You can also look at the running applications in the task manager. Try turning off those that can use sound (players, record players, etc.). If you find such applications, after turning off which sound appears, then you need to remove them from autorun.

3) The sound on the laptop disappeared.What to do: if in sleep mode laptop went with the headphones, then the headphones were taken out and the laptop was taken out of sleep mode. And there is no sound. It helped: go into sleep mode again, but go out with the headphones inserted. That is, repeat the operation in the reverse order (we put it into sleep mode without headphones, and take it out of the mode with headphones already). This can be the case when connecting other interfaces using sound, such as HDMI.

4) If you right-click on the volume icon in the tray, you can see the items for selecting playback devices. Choose playback devices and see if the device is selected for audio playback. You need to choose speakers for listening to sound on your laptop. If you connected a TV, for example, via HDMI, then another device may be selected.

5) If there is no sound only in the video or when playing individual files, then there may not be the necessary codecs. You can download the codecs and install, it's easy to do. Popular set of codecs K-Lite-Codec... You can download and install it.

6) Check if the sound disappeared only in one application or on some website, or there is no sound at all on the laptop when using any programs. Maybe on the site or in one of the applications, the volume control is removed to a minimum, but on other applications everything works fine. For example, both on “YouTube” and when listening to music on the “VKontakte” website have their own sound controls.

I lost sound on my laptop, what should I do? - this question is often heard by technicians. Almost every laptop user has encountered a similar problem.

If you figure out what is the cause of the malfunction, then you can try to solve it yourself without contacting a service center. So, let's try to figure it out.

If you experience sound no longer playing on your computer, there are several explanations. There are hardware malfunctions, and there are software malfunctions.

Hardware indicates a malfunction of the sound card and speakers, damaged connectors, cables. In this case, the laptop must be taken to a workshop. The most common are software.

Software factors include incorrect sound settings in the operating system, player, audio manager, or driver that has been updated.

The main reasons for the lack of sound in laptop speakers

the volume mixer is turned off;
speaker malfunction;
crash in drivers;
problems in the internal control system - "BIOS";
disabling the "Windows Audio" service;
lack of audio codecs.

1 First, check the performance of the speakers if they are connected to the laptop. If they work properly on other devices, then it's all the same in the laptop itself.

2 Start automatic system update. This means creating a restore point when everything was still working. Such actions sometimes help if problems with the operation of the software or individual components appear in the system.

Let's consider in more detail all the ways to solve this problem.

Ways to solve the problem

If you find any malfunction or interference, the first step is to restart your computer.

If after that nothing has changed, then we must look for the reason in something else. But sometimes the reason is very simple and banal.

Perhaps the mute button was pressed on the laptop panel, or on the taskbar at the bottom of the screen on the right.

To get started, just check if all the indicators on the volume bar are turned on, that is, if the volume icon is crossed out in red.

Or the sound has been set to its minimum value. Adjust the volume, and most importantly, check if headphones are connected.

You might just forget about them and not notice that they are connected.

Often, laptop manufacturers supply devices with various utilities, they can automatically change settings.

Look for a key with a picture of a speaker in the keyboard. As a rule, these are three buttons: increase, decrease and mute the volume.

If there is no sound in a laptop with Windows 7 or XP software, then try to press these keys.

As a rule, it is necessary to press simultaneously with the "Fn" key, but in some cases it is not necessary to use it. Make sure the speakers are turned on and the volume is set to normal.

Failure in drivers

A possible cause of audio problems in the notebook is driver interruptions.

When starting to work with drivers, it is important to first determine what exactly is the cause of the breakdown in them.

If the driver of the sound card does not work or it is damaged, then the sound will of course not be played.

There are several reasons for this situation:

software failure;
infecting your computer with viruses;
crash during driver update;
mismatch between installed programs

It is necessary to find out the reasons and find ways to eliminate the malfunction.

Solutions

driver update programs;
through the menu;
download on the site;
from the installation disc;

First you need to try this scheme: open. On the Start panel - "Control Panel"- Then . It will open a tab "Sound devices".

It is worth trying several times to turn it on and off, or turn on the driver update.

If the operating system of the laptop is Windows XP and there is no sound, then it is recommended to diagnose using the Windows Audio system.
And for this you need to enter "Control Panel", then "Administration", then "Services".
Find the line with the name "Windows Audio" in the list, open it.
In the "Launch type" area, you need to define the mode "Automatically".
In the opened window, select the automated selection of drivers.
If the drivers are found, in this case they will be loaded, and then determined by the machine.

But if the drivers are not recognized by the operating system, you will have to install them yourself.

Such as Driver Pack Solutiоn, Driver Updater, Driver Genius PRO, Logitech, Driver Updater, Realtek, Creative. For example DriverPack Solutiоn, all these drivers are free, which can be downloaded and used offline.

The principle of operation is as follows: after launch, the devices installed on the computer are determined, all drivers are automatically installed. The drivers can then be installed on any device.

Most of the websites of manufacturers of laptops and other digital technology have a "Help" or "Support" link.

And on the help page, you can download the necessary drivers for a specific laptop model.

They have support for all operating systems. This is not a complicated procedure, and many sites have programs with autoloading drivers.

Many of the driver packages come with an installer. After detecting the software, the program will automatically install, this should resume sound in the laptop. Then you need to restart your computer.

If your set of drivers does not contain an installer, in this case, in the properties with audio devices, when you click the "Update" command, you must select to install the drivers manually.

If the driver updates did not lead to anything, and the sound did not appear in the laptop, then this means that the new driver is not compatible.

In this case, returning to the initial version of the drivers by clicking on the "Roll Back" function should help.

In the window with the properties of the audio device, click "Yes". To do this, on the "Start" panel, click on the line "Control Panel" then on "Performance and Service", select "System" and by clicking on the "Devices" tab then you will see "Display adapters", and there is an NVIDIA graphics processor, click on the "Driver" command, and finally select "Rolling back the driver".

So, if, in the end, updating the drivers did not work, then you still need to reinstall them from the disk that comes with the laptop.

The algorithm for installing drivers is not complicated, it looks like this:

1 Insert a disc into the drive.

3 The disk contains a file for installation called Setup.exe (Install.exe). Subsequently there will be "Hardware installation wizard", it will install drivers on the laptop.

4 After all the procedures, the system must be rebooted.

5 Then open the volume window and adjust the sound.

Sound control panel

There are a number of essential aspects to be taken into account. “Windows Audio” is a service specialized in the activities of all devices for playing sound in the system.

And in the event that this has disappeared on the computer, then this usually means that the service is inactive. And “Windows Audio” malfunction usually appears when reinstalling the system.

A similar situation appears after the automatic installation of drivers on the motherboard, for this reason it is recommended to install them manually using the function.

One of the many reasons for losing sound on a laptop is the onboard sound card being disabled in the BIOS.

BIOS is a collection of microprograms that make it possible to configure individual devices of the system unit, as well as boot the operating system and other settings of significant parameters.

Literally, BIOS can be characterized by a basic input-output system.

To check this, you need to go to the BIOS menu.

There are several options for logging in by pressing key combinations at boot:

CTRL + ALT + INS
CTRL + ALT + ESC
CTRL + ALT + ENTER

Therefore, immediately after booting the system, if you press, for example, Delete or F2, the Setup message appears and there will be a button next to it, here is the entrance to the BIOS).

This button must be pressed in time when the system is booting.

When the BIOS is entered, you need to find the line "Advanced" and the word "Enabled" should light up next to the inscription "High Definition Audio".

If "Disabled" is on, then select what is needed using the arrows on the keyboard.

Restart your computer and check if there is sound.

I have lost sound on Windows 7, there is no experience in eliminating such malfunctions in this operating system, but I really want to figure out what the matter is and fix the problem myself. You have a similar article about Windows XP, but unfortunately it did not help me. Denis.

Missing sound on Windows 7

The reasons for the lack of sound in Windows 7 are sometimes simple, and often it takes a long time to find the problem. Very often, when asking a question, users give incomplete information about the problem, for example, they do not say that the day before they tried to update the sound driver or tried to connect other speakers to the computer or made changes to the settings of the "Sound" tab in the Control Panel. Or maybe you installed some plug-in on your laptop to improve the sound quality of the players installed in your system and after that you have lost sound on Windows 7... But whatever happens to you friends, do not despair, there is a solution to your problem and, as usual, we will start with the simplest.

Note: at the end of the article, as an option, there is a way to work with a little-known novice user - Windows 7 Universal Diagnostic Tool, it can automatically find and fix various problems not only related to no sound. We also have a new article published, in which you can learn in detail how to establish the exact name of your sound card, how to download drivers for it from its official website, and how to install them.
If you have Windows 8. read our article
If your built-in sound card is out of order, read our article.
If you are not satisfied with the sound quality on your laptop, you can.

Even very experienced users have situations when, for some reason, they disconnected the speakers from the system unit and then forgot about it. Check if everything is securely connected. The speaker output is marked in green.

You can check the soundness of the speakers by connecting headphones to the sound output, if there is sound, then the speakers are faulty. Also, if there is no sound in Windows 7, you need to go to the device manager and pay attention to whether you have an exclamation mark in a yellow circle opposite the Sound devices item. Start-> Control Panel-> right-click on "Computer" and select Properties from the menu, then Device Manager. If the yellow circle is present, it means that the sound driver has simply disappeared and you need to reinstall it.

How to do it? Read our article How to install a sound driver(link above), but on the other hand, the sound driver just does not fly off, which means that some of your actions led to a problem, by the way, Windows 7 has a system recovery service, which you of course know about, so it can be applied in this case.

Note: In order not to puzzle yourself over which of the two hundred programs and games installed yesterday by you led to problems with sound, you can use a simple system restore, since in Windows 7 it is usually enabled for everyone and roll back with the help a little back.

Just yesterday, my friends asked me to fix the problem of no sound on their computer. The day before, they downloaded on the Internet and installed for some reason two multimedia players at once, after which they lost the sound. First of all, I looked at the speaker volume indicator in the Taskbar to see if it had been lowered at all, everything turned out to be fine.

I also clicked on the Speakers button with the right mouse and selected Playback Devices from the menu,

there was a green checkmark on the Speakers item as it should be.

Although sometimes there is no sound in Windows 7, the Sound window displays one Digital Audio (S / PDIF)

or absolutely nothing is displayed, then click on an empty space with the left mouse button and a menu is displayed in which you need to check two items "Show disconnected" devices and "Show disconnected devices"

and we will immediately see our Speakers, right-click on them and select "Enable",

do the same with headphones, then "Apply" and "OK".

Strange, but my friends in the Sound window displayed Speakers marked with a green checkmark and in the Device Manager there was a working sound device with support for NVIDIA High Definition Audio

Everything indicated that everything was fine with the sound. I brought headphones with me and connected them to the audio output located on the back of the system unit and made sure that there is actually no sound, which means that the speakers are also working properly.
First of all, in this case, the sound device driver may be damaged or not working correctly, which means you need to go to the device manager and try to update the driver, which will not always help, in which case you need to completely remove all sound devices from the system.

After the performed operation in the operating system, my friends got a sound. By the way, in this case, you can also use system recovery and of course a complete reinstallation of the driver.
Another time there was a different problem, a person installed Windows 7 on his computer, everything would be fine, but there was no sound, there was eloquent information in the device manager.

In such cases, you need a disk with drivers for the motherboard that came with your computer upon purchase, on this disk you need to see if the drivers on it are suitable for Windows 7. If the drivers on the disk are designed for Windows XP, you should not install them, of course, you need to go online and download native drivers for your sound card on its official website.

How to do this with us is described in detail and step by step in the article. Often not only the search for drivers, but also the correct determination of the device name is a problem for a novice user, so I still advise you to follow our link and read the article. If, nevertheless, you do not find a driver for Windows 7, but you have an installation package of drivers for Windows XP, you can try to install it in the Compatibility troubleshooting mode, but I tell you friends, this is not quite the best option.

It happens to find the reason for the lack of sound does not work at all, if the built-in audio card fails in the device manager, there may be a red circle with a cross in front of it, or there may not be anything, in this case, many decide to completely reinstall the operating system, then install it on the sound card driver and if in this case the sound does not appear, you just need to buy and install a separately installed PCI sound card. It is advisable to buy together with the disk on which the drivers are located specifically for your Windows 7-64bit or 32bit. You also need to know that immediately after you put a separate PCI sound card in the system unit, the built-in one in most cases needs to be disabled in the BIOS, otherwise the sound will not appear. Many people do not attach any importance to this and in vain. High Definition Audio must be Disabled.

A simple sound card of the PCI interface is not at all expensive, somewhere around 100-200 rubles and, for example, I always carry it with me. The first signs of a breakdown of the integrated sound card are from time to time disappearing or poor quality sound. So it's time to replace it with an expansion card.
By the way, individual sound cards of the PCI interface are different, for example, Sound Blaster manufactured by Creative Technology, are in fact a very high-quality and professional solution, though they cost from two thousand rubles.

But keep in mind, if you have such a card, as well as a good audio system, and in some game you decide to shoot from a Kalashnikov assault rifle, then the neighbors may misunderstand this and decide that you are actually firing at home from a submachine gun.

An interesting story about how we searched for the missing sound with our reader.
Denis wrote me a letter stating that he had lost sound on Windows 7-64bit, suspicion of a faulty built-in sound card. Speakers disappear, they were checked on another computer, they were working properly. Reinstalling Windows 7 and installing native drivers from the disk on the motherboard that came with the purchase of the computer did not help. Also, the downloaded driver package from the official Realtek website, after installation, did not bring any result.

Our reader bought and installed a sound card that is installed separately in the PSI connector, before buying, he asked if there was a disk for it with drivers for Windows 7-64bit. Then the most interesting thing is that he puts the side cover of the system unit in place, then connects all cables and speakers, turns on the computer. I remind you that the sound card came with a disk with drivers, which he successfully installed, but no sound appeared. He wrote me 10 letters, we sorted out all the faults that could be with him, but the sound still did not appear, I began to think that the purchased sound card is also faulty, this happens or it is not fully inserted into the PCI slot. Denis, at my request, took the card to the service where he bought it, they checked it with him and it turned out to be working properly.

In the last letter, Denis sent me a screenshot of the system unit and showed his mistake himself, it turns out he still connected the speaker cable to the old built-in faulty sound card, like this. The system unit of our reader was under the table and our friend, according to him, had to act literally by touch, it is not surprising that they made such a mistake and it is forgivable for him, since friends agree, in the absence of experience, the chances of connecting incorrect speakers greatly increase. So I ask you to consider all of the above carefully.

The arrow shows the sound output of the purchased audio card, the place where the plug of the speakers had to be connected, from above you can see the same connector, only belonging to the failed built-in sound card.
