Working on a computer without sound can be very inconvenient. The opportunity to listen to music and watch movies is lost. This article discusses what to do if the sound suddenly disappears on your work computer, how to restore it, and why this might happen.

General information

Conventionally, problems why audio does not work can be divided into 4 classes:

• Problems with audio equipment.
• No contact.
• General computer glitches.
• A specific program is not working correctly.

Some of them are easy to fix, while others will require the help of qualified professionals. For example, if the sound on your computer disappears as a result of a breakdown of audio equipment, you are unlikely to be able to restore it yourself. The equipment needs to be sent in for repair.

Checking this reason is quite simple: try turning it on your phone, audio player, laptop or other personal computer. If there is also no signal, you have identified a problem and can stop diagnosing.

No contact

The speakers are connected to the computer's sound card using wires with 3.5 mm plugs at the ends. First, try the following: pull the connector out of the connector and plug it back in. Do the same on the other end of the wire if it is connected to the speakers using a plug. If you have another wire, try using it, yours may have been damaged. If the sound disappears regularly, most likely the problem is in the wiring. Replace the wire to restore everything

This reason may seem stupid or trivial to you, but many people simply forget about it. Even experienced users personal computer may do a lot of setup things to no avail, forgetting to check the volume level in the system.

If you don't know how to do this, follow the step-by-step instructions provided:

Sound Control Panel

If you have lost sound on your computer and none of the previous tips helped you, try the following:

Sound card drivers

Users often complain that there is no sound on their computer due to a failure of the audio card drivers.

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 included in the kit. special program to automatically search 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 in 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 vary depending on the BIOS version) check the status of the “High” parameter 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!

The reason for this on different operating systems can be completely different things. Let's look at the most common causes and options for eliminating them point by point.
If you did not buy a separate sound card, then the built-in one will most likely be “realtek”, both in the laptop and in a regular PC. On Windows XP, the reason for the lack of sound may be drivers that were not installed, or rather, drivers that were installed incorrectly, or even more accurately installed, but due to a missing operating system update, they did not work. Drivers usually don't work if it's Windows version sp2, because modern drivers are designed for sp3. Let's check point by point all the places where the sound may be disabled or incorrectly configured.
1. And the most banal thing. There is a speaker icon in the lower right corner (tray) of the screen near the clock icon. Click on it with the mouse and see if the “mute sound” checkbox is checked and if the volume lever is lowered all the way down. For novice computer users, this can be a serious problem. Uncheck the box and move the lever up.

2. Check whether the power cable for the speakers is plugged into the outlet, whether the speakers themselves are turned on and whether the indicator on them is on.

3. Check whether the sound plug from the speakers is inserted into the correct sound card socket on the PC. There will be a drawing on the socket indicating a sound wave and an arrow leading from the socket. Motherboards with integrated audio usually have 3 slots or 6 in two rows. The output socket is usually located in the bottom row, centered. Do you think I'm mocking you? No way. 70% of calls regarding no sound result in a check first three points.

4. Also in the tray, if the driver is installed correctly, there will be a second icon with a speaker belonging to the Realtek sound card itself. We stand on the speaker icon with the mouse cursor, press the right key and in the menu that appears, click “Settings”. As a result, you will see a window in which, by moving the dot, you can switch between playback and recording devices. Also below you can see checkmarks on those devices that are turned on. Turn on all devices, raise their volume levers up and check the “Mixer” checkbox in the playback devices as the main device.

5. Install Windows update up to 3 sp. If you don’t know how, just run it on your machine “ Automatic update"and wait until it downloads and installs all the add-ons. To do this, go to “Start” - “Settings” - “Control Panel”. We find the “Automatic update” icon, set it to “automatically download and install” and wait. After installation, reboot. If you have a left-hand broom, then you should not do this, because the license will be checked and it will not turn on after that.

6. Check to see if the sound card driver is installed at all. To do this, go to “Start” - “Settings” - “Control Panel”. Find the “System” icon and launch it. In the window that appears, go to the “Hardware” tab and click the “Device Manager” button. We find “Sound devices” in the list, click on the plus sign next to them. Let's see if there is a realtek sound card in the list and if there is a yellow question mark next to it (wrong driver). There may be nothing at all in “Sound devices” and this means that the driver is not installed at all. If you have a separate sound system, then you should try reinstalling the driver from the disk that came with it. If there is no disk, then you can try to read the name on the card itself and its markings in the form of numbers, and then try to search the Internet for drivers for your version of the operating system (although if you are an inexperienced user, it is easier to call a wizard). If you have a standard motherboard with an integrated card, then it is quite possible to assume that the included drivers are not suitable and try to download a more recent version from the Internet. For Realtek it’s simple, because the drivers are standardized for different motherboards and card versions, and you just need to download latest version updates. Usually called Realtek High Definition Audio R270 (the version number is constantly growing, so look for the latest one). When downloading, try to download drivers from the websites of your equipment manufacturer. Also pay attention to how many bit operating systems you have (32 or 64 bit). To do this, go to “Start” - “Settings” - “Control Panel”. Find the “System” icon and launch it. In the window that appears, go to the “General” tab and look at the system version. After installing the drivers, we reboot.

Why is there no sound on Windows 7? Perhaps many Windows users 7 this problem has occurred at least once. This article contains the most common causes and ways to solve them.

The main reasons leading to loss of sound, as well as ways to solve them

Why does the sound disappear on a laptop, computer, etc.? In most cases, the reason for this is the user's own errors in handling the operating system.

So, what to do if the sound on your laptop does not work. The first step is to check the availability of the necessary drivers for your sound card. Perhaps they need updating, or you don't have them at all. By the way, driver errors are half the reasons why sound on a laptop disappears. In order to see which devices on your laptop or computer need driver updates, you need to open the device manager, which can be found in the control panel.

The manager window organizes and presents all drivers installed on a laptop, computer, etc. Using it, you can check the availability, functionality or relevance of drivers. If any item is marked with a yellow triangle, you should pay attention to it! Devices responsible for sound playback are located in the “Sound, gaming and video devices” tab.

Perhaps the most banal, but at the same time the most common reason for which the sound disappears is its unconscious turning off in the mixer. A mixer is a system that allows you to adjust the volume of specific applications. You can open the mixer by clicking on the corresponding inscription in the volume control window. After starting the mixer, make sure that all parameters are non-zero.

No less common is another reason why the sound on a laptop or desktop computer disappears. Its essence lies in the system disabling the output devices themselves. The reason for this may be system errors, device configuration changes and user intervention. To correct this problem very easy! For this:

Another common reason is that the service responsible for playing audio is disabled. To start it again, you need to go to Control Panel - Administration - Services. In the window that opens, find the “Windows Audio” service.

If the service is disabled, double-click on the service to open the settings window, from where you can force the service to start by clicking the “Run” button.

In this window, you should configure one more parameter – the startup type. This parameter is responsible for starting the service when booting Windows. In order not to constantly start the service manually, I advise you to define this parameter as automatic.

No sound from the front panel

What to do if there is no sound on the front panel or no sound at all? The whole problem lies in the question “Why is there no sound?”

In most cases, the front panel requires Realtek dispatcher. If for some reason you don’t have it, be sure to reinstall it. After launching the manager from the control panel, go to the “Speakers” tab. Next, double-click the folder icon in the upper left corner and check the box next to “Disable front panel slot detection”

If, after completing the operation of displaying information on the front panel, the panel is still missing, it means that the BIOS installed in your laptop or computer is most likely incorrectly configured. The BIOS system is present in any laptop, computer or tablet, and provides the operating system with API access to the hardware, including the front panel. To configure the BIOS for the front panel to work, you need to:

1. When the system starts, namely while demonstrating the logo of the motherboard manufacturer installed on your laptop or computer, press and hold the “F2” key to exit to the BIOS menu.
2. Then you need to find and select “Onboard Devices Configuration” in the “Advanced” tab.
3. In the next window, you need to configure one parameter, namely “Front Panel Type”, which is responsible for the type of front panel. There are usually 2 options: HD Audio and AC97.

Exactly what type of front panel hardware you have should be indicated on the motherboard or wires.

If even after setting up the BIOS system there is no sound on the front panel, then the sound card may be damaged and will have to be replaced, but in this case the sound should disappear not only on the front panel. The sound may not be working because the wire has come loose.

Problems with functionality PCs can occur for various reasons. However, there are many solutions to solve this or that problem. But in Lately many users are increasingly searching for search engines articles with query: No sound on the computer, what should I do? in a similar situation?

Let's look at 10 reasons that directly affect sound reproduction.

The sound may not be played for a trivial reason: the volume slider is at minimum or even at 0. Click on the speaker icon located in the tray and make sure that the volume level is not set to minimum.

Also, you can immediately pay attention to the button located at the bottom of the slider. It allows you to turn off the sound completely. Perhaps this is the reason, because even if the volume level is at maximum, there will be no sound coming from the playback devices.

There may also be problems with playback in one or more specific programs. In this case, you need to open the volume mixer and also move the slider from minimum.

Don’t forget also that if your headphones are connected through speakers, playback will only be played through them, and nothing will sound from the speakers.

Setting up playback devices

If you have multiple playback devices connected to your computer, the problem may be that the specific speakers are not selected as the “default” device. To do this, right-click on the same speaker icon and select the “Playback devices” line.

Take a close look at the list of displayed devices and make sure that the speakers have a green check mark indicating that this device is the default.

If there is no checkmark, right-click on the speakers (or on another device that should act as playback equipment) and click on the “Use as default” line.

If the speaker icon is displayed in black and white, this means that the device is disabled. To enable it, you also need to right-click and click on the Enable item.

In case of absence desired device in the list provided, you need to enable the display of all disabled devices. To do this on any free space right-click and check the “Show disabled devices” checkbox, after which you can enable them and set them as the default device.

Checking the functionality of the sound card

If the sound still does not play, you need to check whether the sound card is turned on? To do this, Right-click on “My Computer”, then click on “Manage” and select “Device Manager”.

Expand the Sound Devices menu and make sure your sound card is enabled. If this is not the case (the icon shows a down arrow), right-click and select the “Engage” line.

If they are not on the list at all sound devices, find the “Other devices” item, where most likely, in this case, the device you are looking for will be displayed, but without installed (outdated) drivers.

The issue of driver installation is discussed in the next paragraph.

Installing the sound driver

The most suitable way is automatic search drivers. To do this, right-click on the device and click “Update Drivers”, then select automatic search. If the system finds a suitable one, it will automatically install it and you only need to wait. If the search is unsuccessful, you need to download it from the official website. To do this, you need to know the full markings of the sound card. You can find it in the documentation of this device, or use special application AIDA64, where a list of all connected devices will be presented.

Having received the full name of the sound card, find the latest version of the driver for yours on the official website. operating system and download it.

Right-click on the unidentified device again and search directly on your PC.

In the search folder selection field, enter the address where you downloaded the driver.

After this, the installation will start.

Note: For audio cards manufactured by Realtek, you can download Realtek High Definition Audio Driver, which will help not only restore sound, but also easily connect other devices, such as a microphone, in a special application window.

To open this window, just click on the icon in the tray (shown in the screenshot).

If the drivers were previously installed, but there is no sound, you need to update the drivers. To do this, right-click on the speaker icon in the device manager and open the “Properties” item, then, in the driver tab, click on the “Update” button.

Checking the physical connection of the speakers to the computer

Turn system unit so that you can clearly see all the connected wires. Make sure the speaker connections are stable and firmly seated in the jack. Also pay attention to which connector the plug is inserted into, because, in 99% of cases, it should be connected to the green connector.

Enable Windows Audio Service

Sometimes after critical failures, some services are disabled, including the one responsible for sound playback. To restart it, follow these steps:

• press the Win+R combination and enter services.msc in the window that appears;

• find Windows service Audio and make sure that the Status column shows “Running”. If this is the case, you can close the window, but if not, the service must be resumed. Right-click on it, and then “Properties”;

• in the “Startup type” field, set the value to “Automatic”, then “Run”;

• save changes.

Checking the functionality of playback devices

It’s clear that you’ve probably already checked your speakers or headphones, but still, connect them to another computer, TV, or player to make sure they’re working. If there is no sound when connecting to other devices, then the problem is with the speakers (headphones).

BIOS setup

If you cheated BIOS settings, you could accidentally touch the sound settings, turning off playback. Find the High Device Configuration line in the Advanced tab and if it is not set to Enabled, do so.

Virus attack

And although viruses rarely affect services and sound drivers, this also needs to be checked. Scan your system with an antivirus program and, if found, delete any malicious files. Next, you will have to go back and start checking from the first point.

Restoring or reinstalling the OS

This extreme step can only be performed if you have lost sound in certain moment(day). This could happen, for example, due to an OS update. Open the “System Restore” window and select the restore date when you were sure the sound was working.

If none of the solutions mentioned helped in restoring sound, it is most likely that your audio card is broken, and in this case without service center Or purchasing a new one is not enough.
