How to turn on the sound does not work. Five main reasons why there is no sound on your computer

The most common reason for no sound is turning it off or setting the volume to minimum. If there is no audio playing on your computer, hover over the speaker icon in the tray (right corner of the taskbar). The tooltip will indicate the current volume value. If the sound does not play in a separate application, check its settings. If it is enabled in the settings, audio playback in a specific program may be limited in the mixer. To check, right-click on the speaker icon and select “Open Volume Mixer.” There you can turn on the sound and adjust the volume level for each program running on the computer.

Check the volume on the playback devices themselves: headphones or speakers. When using speakers, also make sure they are connected to power and the power button is in the active position. Checking speakers or headphones is quite easy. To do this, just connect any other device to the audio output instead of a computer: a smartphone, a player.

Important! Also check your speaker settings. To do this, go to “Playback devices”, and in the context menu of speakers or headphones, click “Properties”.

Incorrect operation of audio drivers

Another common reason why there may be no sound on a computer is missing or damaged audio drivers. To identify this issue, hover over the audio icon in the tray. If the message “No audio output device is installed” appears, the problem is caused by the audio drivers.

To resolve these difficulties, right-click on the same icon and select “Detect sound problems” from the context menu.

This will open a troubleshooting window. Wait while the audio diagnostics run on your computer. Depending on the speed of the device, the process can take from a few seconds to a couple of minutes. If the determination of the cause of the malfunction stops at one place, click “Cancel”.

When the sound diagnostics are completed, the system will offer you a choice on which device you want to troubleshoot. In this case, you need to note the device used based not on its type, but on the location of the audio input. For example, if your speakers are connected through the audio input on the front of your computer, check the second box even though it says headphones.

If there is a hardware fault, the diagnostic result will be the following window. It may indicate damage to the speakers or headphones, but most often the cause of difficulties in the operation of audio devices is broken or damaged connecting cables.

At the last step of sound diagnostics, the result of its execution will be displayed. If the problems are resolved, close the troubleshooter. If the diagnostics did not help, click “View additional options.” You can also find help information about the causes of malfunctions by clicking on the “View additional information” link.

Incorrect connection or installation of the device

Sound may not work due to improper connection or installation of audio devices. To resolve this issue, check that the correct input is selected to connect your device to your computer. Speakers or headphones may be connected to the microphone input, causing them to not work.

Go to “Control Panel -> Device Manager” and check the status in the “Sound, Game and Video Devices” menu. If a yellow mark with an exclamation mark is displayed next to the name, the cause of the problem is incorrect installation or malfunction of the device

Note! If your audio hardware is not showing up in the manager at all, update the configuration in the Actions menu.

Right-click on your audio hardware and select Properties, then go to the Driver tab in the window that opens. To update the configuration, click the "Update" button. Here you can remove the driver to reinstall it later.

In the next step, select where you want to search for sound drivers. Two options are offered: automatic search, which includes a search on your computer and the Internet, as well as a simple search for drivers. It is recommended to select the first option to detect drivers.

Important! If the sound card is outdated and its driver is on a separate disk, first copy it to your computer.

The scanning will take about 20-30 seconds, after which a message will be displayed in the search window indicating the successful installation of new audio drivers. If the device already has the latest available driver installed, the configuration will not be updated.

If updating the drivers did not bring the desired result and the device still does not work, it is recommended to remove it from the system. To do this, right-click on the name and select “Delete”. Confirm the deletion in the dialog box by clicking "OK".

After this, you need to update the list of equipment in the “Action” menu. A search will be performed for devices connected to the computer. If the desired device does not appear after searching, restart the manager.

When the speakers are found, their installation will begin automatically. This process may take several minutes. When finished, a message will be displayed indicating that the speakers have been successfully connected and are ready to use.

Damage to connecting cables

Standard 3.5 mm connectors can fail as a result of mechanical damage. Typically, failure occurs at the base of the connector - at the junction with the audio cable. The break may also be in the cord itself. The cause of damage is most often pinched by furniture (table legs, chair wheels). The cable can also be chewed by pets. You can diagnose a breakdown visually or by connecting another cable to the speakers.

Physical breakdown of audio equipment

There may be no sound on your computer if the speakers or headphones you are using fail. This is not difficult to determine - just connect another audio device to the same audio input. If it works, the reason is the broken speakers, and not the computer settings.

Windows Audio Service Disabled

Another common reason for no sound is that the Windows Audio service is disabled. This background process is responsible for processing audio data and is always running by default on a running computer. But if you make changes to the system settings, the Windows Audio settings may be incorrect. The service can also be disabled by malware.

The disappearance of sound on a computer is an unpleasant, but completely solvable problem. After reading the information below, you will learn why the sound on your computer may disappear and what to do in such situations.

Hardware connection problems

First of all, check that the hardware connections of the speakers are correct. The recommendation is especially relevant for families with children and animals, who may accidentally pull out the plug. Make sure that the speakers are connected, the plug is seated tightly and does not dangle.

Check that the plug is inserted into the correct socket. As a rule, the speaker jack is light green, the microphone jack is pink, and the jack for recording from external equipment is blue. The diameter of each of these outlets is 3.5 mm, i.e. It is not difficult to insert a plug into an adjacent socket by mistake, but the sound, of course, will not work.

Problems with speakers

Is the plug in place? Make sure the speakers are working properly. To do this, connect them to any other device that can play music. Alternatively, you can connect any other headphones or speakers to the computer instead of the “silent” equipment.

Volume problems

A trivial, but quite common reason, occurring mainly among inexperienced users. Pay attention to the state of the corresponding icon. Click on it and set the appropriate volume.

Driver problems

After making sure that there are no hardware problems, check your computer for software glitches, primarily in relation to drivers. If there are no drivers or various kinds of problems arise with them, the sound settings icon will look like this. Click on the icon.

The troubleshooting menu will open.

Set the default speakers (if your computer is equipped with external speakers) and click “Next”.

After waiting a bit for the system to complete the required actions, click “Apply this fix.”

The system notifies you that the problem has been successfully resolved. Close the notification and check the sound.

The situation when the mentioned drivers are not included in the operating system by default occurs mainly when the computer is equipped with a rare sound card from a little-known manufacturer. In this case, you will have to install the drivers yourself, using the disk from the kit, a special program for automatically searching for drivers, or by going to the equipment manufacturer’s website.

Problems with BIOS settings

The sound may disappear due to the built-in sound card being disabled in the BIOS. To check, you need to go into the BIOS (on desktop computers, it is usually launched using the Delete key a couple of seconds after pressing the power button) and in the “Advanced” or “Integrated” section (may change depending on the BIOS version) check the status of the parameter "High Definition Audio". Your task is to set this parameter to Enable.

Problems with the Windows Audio service

The computer may be “silent” due to the mentioned service being in a deactivated state. In the Control Panel or through Search, find the Administration section.

Otherwise, you need to double-click on the Windows Audio service line and set it to automatic startup type. Having set the necessary parameters, click Apply.

Restoring sound through troubleshooting service

You can try to get rid of the problems that have arisen using a universal diagnostic tool. We find the “Troubleshooting” section through the Control Panel or through Search (depending on the OS version and personal preferences).

The system is trying to detect problems.

After some time, the service will tell you about the results of studying the state of the system. In the example under consideration, the sound disappeared due to a decrease in volume. To solve this, simply set the volume to the required level.

Sound card problems

If the above methods did not allow you to get rid of the problem, with a high degree of probability the problem is directly in the sound card. In such a situation, there will be no other choice but to buy a separately installed sound card or contact a repair service to replace the failed component.

The simplest and easiest to install option is an external sound card connected via a USB connector. Installing such a component does not require any special skills from the user and eliminates the need to contact a service center.

Respond in a timely manner to emerging problems, do not panic, act in accordance with proven recommendations and everything will definitely work out. Good luck!

Typical problems with Windows are mainly due to the fact that the hardware in the computer was not configured correctly. For example, speakers or speakers may not work. There is no sound on the computer for various reasons, so first you need to put aside panic and try to restore normal operation on your own.

Checking the equipment

Can't listen to something? Let's dive into the underlying reasons for the lack of sound and try to configure the sound card. You need to be sure that everything works properly on the computer. To do this you need:

• Open the Start menu and select Windows Control Panel.
• Then click on the System and Security category.
• Then, in the special System section, click on Device Manager.
• If you are asked for a Windows administrator password, you must enter it.
• After this, you need to double-click on Sound, game and video devices.

Now you should see if there is a sound card in the list that opens. If it is not there, you should read the manufacturer's instructions on how to set it up. It is also useful to look at the Other devices tab; your sound card may be there. A laptop is usually easier to set up in this regard, since there is no sound card. Instead, a special sound processor works.

Sound in Windows may not work if there are problems indicated by a yellow question mark next to the sound card:

• You need to right-click on the sound card and select Properties.
• Then you need to go to the General tab and check the Device Status.

Usually, in such cases, sound in Windows can be restored by simply installing new drivers on the computer. If you don’t have time to scour the Internet for a long time to find and install the necessary driver, you can try a good program called Driver Genius.

After this program is launched, it finds all the necessary drivers on the network (including for sound) and can independently install or restore them in Windows.

Checking the connection

If there are speakers, but there is no signal from them, then you need to check whether they are connected correctly. On almost all computers, sound comes from three connectors that connect to the sound card. It is important to understand here that the speakers must be connected to the linear audio output.

But what if you are not sure which connector is responsible for what? In this case, it is worth going through all the options on the computer, alternately connecting to each socket. The same goes for headphones. It is interesting to know that in almost every computer, after connecting headphones, the sound is turned off automatically.

Power check

The speakers may simply not be connected to the power supply, so there is no sound for physical reasons (no current). Naturally, you need to connect the speakers to the network, and the speakers will start playing sound. The same applies to the controls through which the speakers increase and decrease the volume. Often on laptops the volume control is turned to minus, so that small speakers simply cannot be heard.

You need to open the volume through the following path:

• Click the Start menu;
• Then select Control Panel;
• Click Hardware and Sound;
• Next is Sound;
• Finally, adjust the volume.
• Then the volume slider needs to be raised up.

It is important to ensure that the sound is not completely muted in the mixer. Also, some laptop models have external wheels in order to regulate the sound sent to the speakers. This wheel needs to be checked.

Checking programs

But what if, after all these manipulations, you still couldn’t configure it? It's okay, you just need to check the volume level in the programs installed on Windows. Perhaps it simply does not reproduce anything there. Each program has its own controls so that you don’t need to switch to Windows settings, but quickly turn down or turn up the volume. So it’s better to check the settings everywhere (speakers, headphones, settings) in order to eliminate all the reasons for the lack of sound on the computer and then restore normal operation.

Various operating system errors directly depend on users. It is enough to download a malicious program that attaches itself to free files on the network, and problems with normal operation will begin. However, if you keep a record of all the software that is installed and uninstalled, you can keep your system under control. This is how the speakers will sound, the picture will be displayed correctly, and the programs will function correctly.

This article was written specifically to help users solve any problems related to sound. After all, if there is no sound on the computer, then there can be quite a lot of options for the problem, and searching throughout the network for your specific case is very time-consuming and inconvenient. In addition, the Internet is full of articles that are outdated in their content, which discuss ways to fix them in the operating systems Windows XP, Vista, or at best Windows 7. Now I will tell you what to do if the sound does not work in Windows 10. There are several reasons why there is no sound in the system, and we will look at them all.

7 possible reasons why there is no sound on the computer

The most common case, which is mostly solved in half a minute. It's no secret that for the device to work, it needs to be connected correctly. If the speakers or headphones do not work, check where the wire responsible for the sound is inserted. Typically, the system unit has two or three outputs responsible for sound. They are called linear and look like this:

The output we need is green. As a rule, one is placed in front of the system unit, specifically for connecting headphones, and the other is behind. If you see several audio outputs on the back panel of the system unit, try checking them all. It’s just that one of them is connected to the motherboard, and the other belongs to the sound card. Insert headphones into all outputs one by one and listen for sound.

From the speakers there is a cable, at the end of which there is a plug, usually framed with green plastic or rubber. It is this that needs to be inserted into the linear output, also marked in green. And yes, check if the speakers are plugged in and if the power indicator on them is on. Sometimes something as small as unplugged speakers can make people think their computer is irreparably broken.

Advice: “Always carefully read the instructions for the equipment, this will help to avoid many problems.”

Reason #2: The sound is simply turned off

A common situation is when you accidentally turn off the sound on your computer while doing some work. To turn it on, you need to resort to the volume control located in the lower right corner of the monitor, which is a drawn loudspeaker. Rice. 0. You need to click on it with the mouse. If you see a picture like this,

then the MUTE key was used (complete instantaneous shutdown).

Or do you see something like this:

here the sound is reduced to a minimum and also does not work. Using the mouse, turn on the sound and set it to the desired level. If the volume control is fine, something may be wrong in the speaker settings. Click the Start button in the lower left corner, then find Settings.

Here are all the settings of our computer, including sound. Type “Sound” in the text field and you will see the complete sound settings of your computer in the drop-down list. Press Enter.

Find “Manage audio devices” in the list and left-click.

A window with audio device settings will open.

Make sure your device is on the list and has a green check mark. This means that it is running and functioning properly. Next, go to its properties.

Take a close look at all volume controls. They should be set to maximum and there should be no crosses anywhere, like in the picture.

Advice: “If you don’t know what will happen when you click on an icon, then it’s better not to click.”

Reason #3: Sound card is damaged

This is a more complicated case, but also quite solvable. First, you need to determine that it is the sound card that is broken. Moreover, now we are considering physical damage, not software. That is, the card burned out or failed.

Open the system unit and visually determine where the sound card is located. It is usually inserted towards the bottom of the motherboard and secured with a latch. At the back it has a line output where speakers are connected. Carefully remove the card and clean it from dust if necessary. Look carefully to see if there are any swollen parts or visible damage on the surface.

Try inserting a different sound card (you can borrow one from a friend) or connect the sound cable to the line-out port of the motherboard.

If sound appears, you will have to buy a new card to replace the burned one, or use the built-in sound card. Remember that sometimes simple cleaning can restore the device.

Advice: “Always keep the inside of the system unit clean and it will work much faster.”

Reason No. 4: drivers are not installed (damaged)

In order for any computer device to work, it needs a special program. It's called "driver". Whether it's a mouse, keyboard, or anything else, they all need to have the correct drivers or they simply won't function. Let's check if you have the correct driver installed on your sound card. Go to Settings, then type Device Manager in the search bar.

Click on it. We are interested in the item “Sound, gaming and video devices”. It contains everything that is installed on your system.

As you can see, opposite the two devices there is a black arrow in a circle. This means that the device is not currently in use. And if a yellow triangle or the words “Unknown device” is shown there, then you need to install the driver.

Right-click on it and click Properties. A window with device properties will open. This is where you can update, remove or roll back the driver.

First, click on “Enable”, this will turn on the device if it is currently disabled.

If there is no driver (the yellow triangle is lit in the “device manager”), click “Update”. The driver will automatically update; you just need to choose where to look for the driver, on your computer or on the Internet.

“Roll back driver” returns the previous version if any problems arise during installation.

“Delete” is the last resort. The device is completely removed from the system. Then you need to restart the computer and, perhaps, this time the system will correctly detect the sound card and automatically install the necessary driver. In this case, you must be connected to the Internet, since Windows 10 uses its driver database, downloading them from the network. Then you need to check the sound, most likely everything will work.

Advice: “If your sound card came with a disc, install everything you need for the device from it. This is the best way to get the device to work correctly."

Reason No. 5: The Windows Audio service is disabled on the computer

Everything that happens on your computer is controlled by Windows services. Sometimes, due to certain software problems, these services begin to work incorrectly, which leads to errors, and in our case, to the fact that there is no sound.

To check that the service we need is running, go to Settings, type Services in the text box, and then click View Local Services.

In the window that opens, find the required “Windows Audio” service.

The word “Running” must be present next to it, otherwise the service is disabled. Using the right mouse button, call up the context menu and select the “Run” sub-item in it.

Advice: “Don’t mess around with system settings, this can lead to irreparable consequences.”

Reason No. 6: a computer virus is to blame or programs are conflicting

If the sound suddenly disappeared when you were not doing anything, or after restarting the computer, then there is a high probability of infection with a virus. Most of them do not affect audio devices, but some create problems that completely block sound from the system. Many antivirus programs do not always find such viruses, and if they do, they remove them so that the sound still does not appear.

To solve this case, I recommend that you install the EMSISOFT Anti-Malware program. Being, in fact, a utility, it does not conflict with any antivirus and instantly removes malicious objects. You can download it from our website; in addition, there is a free 30-day version of the product. After installation, click “scan for threats” and the program will find all viruses in the system and restore its functionality.

If the sound disappears after installing a certain program, simply uninstall it and reboot the system. Typically this should help.

Reason #7: Audio codecs are not installed

It also happens that system sounds are played, but when playing music and movies, there is complete silence in the speakers. How, in this case, can you restore sound on your PC and fix the problem? Since there are a huge variety of sound formats, there is a special thing so that they all work and run on one computer. It's called a "codec". For example:

• WMA and so on.

Each of them is needed to launch and work correctly one of the audio formats.

In order not to go through and install them all, there are special assemblies that include most of the well-known codecs. The most famous assembly is called and it consists of a huge archive of sound codecs that allow you to play any known audio formats.

After installation, everything will turn on automatically and problems with no sound are guaranteed to be corrected.

Tip: “Always keep your codec database up to date.”

That's all. I hope the article was useful to you and the question of how to connect sound on a computer is no longer a problem for you.

Knowing about all possible problems related to sound in Windows, you can easily determine why the sound is not working and fix it immediately.

You don't need any additional hardware or software to do this. Most sound problems can be resolved with a couple of straight hands and standard Windows software.

Causes and solutions

The cause of sound problems can be either an incorrect setting of the volume control on the speaker or a failure of the sound card.

All causes of sound problems can be divided into 3 groups:

Problems with sound-reproducing equipment can be solved by simple diagnostics:

1. checking connections to the computer;
2. Network;
3. setting up hardware volume controls.

Hardware problems can be solved by repairing, checking the connection, or replacing the sound card. And if only a specialist can repair the sound board, then checking the connections and also replacing the board with a new one can be done by an ordinary user. To do this, you will need to understand a little about your computer.

Software problems are the most common audio problems. They arise due to incorrect configuration or installation of sound drivers, system utilities, or individual applications.

Determining the cause of a software problem is the most difficult task, but completely solvable with the right approach and sequence of actions. Such problems can be corrected by reconfiguring the software, reinstalling drivers, and in some cases restoring the system or reinstalling it.

Video: what to do if the speakers don't work

Sound not on

Sometimes the reason for the lack of sound is not due to problems, but to the fact that the sound is simply turned off, and we keep asking ourselves: why doesn’t my sound work?

On a computer running an operating systemWindowssound control is performed:

1. on a sound-reproducing device;
2. in Windows system settings;
3. in the utility settings for the sound card driver;
4. in the settings of a specific program.

If there is no sound on your computer, you should first check the hardware volume control on your speaker system, speakers, or headphones.

To do this you need:

• open a folder with standard audio recordings;
• enable playback of one of them in a standard player, for example Windows media.

Such a sound recording, if the system is working properly, should be played “out of the box”, that is, with standard pre-installed operating system software without installing additional software. That is, if everything is in order with the system itself and the speakers, the sound should be played.

In all operating systems of the Windows family up to and including XP, the folder with standard audio recordings is called “my music” and is located in the “My Documents” directory.

ABOUT t “seven” and older, this folder is called “music samples”. And it is located in the directories: “system disk” “users” - “general” - “general music”.

On the sound-reproducing device itself, you need to check the position of the volume control, the connection of the device itself to the electrical network and to the computer. The speakers themselves may have a power button, which should also be checked to turn on.

Important: The plug for connecting the speakers to the computer, as a rule, also fits into other connectors on the sound card. But the sound will only work if the plug is connected to the correct socket. On a sound card, such a connector is usually marked with a picture of a speaker and is green, like most speaker plugs and speaker systems.

If after checking the speakers there is no sound, you can check their functionality with another sound source, for example, a DVD player.

You should also check the sound performance with other speakers or headphones. If sound appears after these steps, the speakers should be replaced or repaired. If there is still no sound, the problem is something else.

Missing or incorrect drivers

If there is no sound on the computer, suspicion falls primarily on the driver.

After all, there will be no sound if:

• driver not installed;
• An outdated version of the driver is installed;
• The driver is not compatible with the device.

Modern operating systems of the Windows family have a built-in standard audio driver that is compatible with most well-known sound cards. Older operating systems do not have such standard drivers, and some sound cards are not supported by standard OS drivers.

Therefore, if you have a clean, modern operating system installed, but it does not play sound, you need to use special drivers for your sound card.

Such drivers are usually supplied on a CD along with the sound card.

If there were no such disks or they are lost, the drivers can be downloaded from:

1. official website of the sound card manufacturer;
2. official website of the laptop manufacturer.

Information about the sound card manufacturer can be found:

If the passport to the computer is lost, and nothing is indicated on the sound card itself, you can use the special “Everest” utility, a trial version of which can be downloaded for free on the Internet. This utility allows you to obtain information about the manufacturer and model of any computer part, from the USB node to the processor.

If you do not know whether the driver is installed or not, or whether the driver is working properly, you can check this using standard Windows tools.

To do this you need:

In order to update the driver you need to:

If for some reason the installed driver turns out to not only not work, but also conflicts with other computer software, it must be rolled back. Driver rollback not only removes but

Important: After any operation to install or reinstall the driver, the computer must be restarted.

To install the driver you need to do the following:

1. Most sound card drivers come with startup files. by clicking on such a file, the installer is launched, following the simple prompts of which you can install the driver and immediately perform its necessary configuration;
2. if the driver is supplied without an installer, it can be installed in the same way as updating the driver;

Video: What to do if there is no sound on the computer

System Restore

If, along with the loss of sound, the computer begins to display system error messages, most likely a system failure has occurred, which can be corrected in two ways:

1. restore the system;
2. reinstall the system.

Important: System recovery in Windows is performed using checkpoints, which must be created in advance of problems with the system. If there are no restore points, it will be impossible to restore the system.

In order to restore the system you need to:

It is better not to use the computer during the system recovery process. The system will notify you with a message when the restoration is complete.

Inoperability of the sound output device

You can check the functionality of your sound card in several ways:

In the first case you need:

If the window displays that the device is turned off and the system does not allow you to turn it on, there is most likely a hardware problem with the sound card.

An easier way is to connect USB headphones to your computer. This gadget is equipped with an external sound card that works out of the box, so if you hear sound in your headphones on your computer, the built-in sound card is most likely faulty. The absence of sound in USB headphones will indicate that the problem is not hardware.

Checking the Audio Control Service

To do this you need:

• Click on the “Run” button in the “Start” menu. In the window that opens, enter the command services.msc;
• in the services window, select the “window saudio” service;
• if it appears that the service is disabled, you need to double-click on it to enable it.

Diagnosing and fixing audio problems varies slightly between operating systems.

WindowsXP

XP does not have a search function for programs from the start menu. Therefore, in order to open this or that utility discussed in this article, you need to know its location. For example, the system restore utility is located at: control panel – system – “system restore” tab.

Windows 7

“Seven”, unlike XP, has a built-in utility for automatically diagnosing and eliminating system problems, including those with sound. This function starts automatically, but it can also be started manually directly from the window where the problem occurred by clicking on the corresponding button.

Reinstalling modem drivers

Windows 8

This version of the operating system does not have a start menu, which we used to access some system settings. “In Eight” you can access any utility by simply entering its name in the Metro search window, which opens when you hover your mouse over the lower right corner of the desktop.

Windows 10

In the latest version of the operating system, the start menu and metro menu work simultaneously. At the same time, the search window necessary for diagnosing sound problems has been returned to the Start menu. Therefore, troubleshooting problems with sound in this operating system is carried out in the same way as in the usual “seven”.

Why doesn't the sound card work on my computer?

The sound card on your computer may not work in two cases:

• it is faulty;
• It is not connected to the computer correctly or its contacts are loose.

To understand whether the sound card is working or not, you need to eliminate contact loss. for this you need:

• carefully unscrew the cover of the computer system unit;
• Disconnect the sound card and insert it back until it clicks.

A sound card is a card with connectors for speakers; it connects directly to the motherboard, usually via a PCI connector. To disconnect a poorly secured sound card, you need to release the latches located on the sides of the slot, and then pull the sound card towards you.

If after these manipulations the sound does not appear, the sound card is most likely faulty and needs to be replaced.

Audio Manager

Any Windows operating system has a built-in sound manager, incorrect configuration of which may be the reason for its absence. Some sound card drivers are supplied with a proprietary “sound manager” utility.

Sound managers are accessed through the volume control in the taskbar tray and a special branded manager icon next to the volume control. The manager allows you to assign a default audio output device. Wrong choices can sometimes cause absences.

To check the dispatcher, you need to:

Registry

Through the operating system registry, you can make the most subtle system settings. But changes in the registry can lead to reassignment of the sound card slots, which will lead to no sound.

This problem can be corrected by changing the binary parameterpin01, responsible for the rear green socket, which should be used for audio output.

To do this you need:

Important: If you are not sure what actions you are performing in the registry, it is better not to change anything. Actions with the registry are irreversible.

Jumpers on the motherboard

On some, especially older motherboards, there are jumpers that switch the audio output from the front panel to the rear panel and vice versa. If the jumpers are set incorrectly, there may be no sound.

For sound to appear you need:

1. Unscrew the cover of the system unit;
2. close contacts 5-6 and 9-10 with jumpers.

Uninstalled audio codecs

In some cases, a problem with sound is essentially a problem with playing audio files of a certain type of codec for which the system does not exist. Therefore, it is recommended to check the functionality of the sound using files in wma or wav format. Codecs for these formats are included in the basic version of any operating system.

To play the sound of other audio formats, you need to download a codec package, for example K-lite, or install a player that uses its own codecs, for example GOM or VLC.

Front Panel

The reason for the lack of sound on the front panel may be:

• incorrectly set jumpers on the motherboard;
• lack of connection of the front panel to the motherboard.

Very often, computer assemblers build in the front panels of audio connectors for the model, without connecting them to the motherboard. In order to connect the front panel to the motherboard, pin cables are used that come with the panel.

You need to connect the pins to the front panel block of the motherboard, which is usually located in the lower right part of the board.

Competition between several drivers

Even if all drivers are installed, they may not work due to conflict with each other.

This problem is solved as follows:

• updating all drivers to the latest version;
• installing only original drivers.

On laptops, a driver set that differs from the factory configuration may conflict. You can find out the basic set of drivers on the official website of the laptop manufacturer in the “support” section.
