What to do if there is no sound. Why speakers on the computer do not work if they are turned on

Hi all! Modern computer user (unless of course you are not an office worker) hard to imagine without music. The lack of sound on the computer is quite sad, because even this note I am writing with a calm track in the background (otherwise blog posts would be dull and uninteresting). So, I want to tell you about my experience and answer the question - why is there no sound on the computer?

With the transition to Windows 10 and the advent of HDMI (where video and audio are on the same cable and your graphics card has an audio chip) there were even more problems ... this is especially true if your computer is not the first freshness, although it did an excellent job with the tasks set on Windows 7.

The first thing to do if there is no sound on the computer is to check the cables and make sure that the speakers (or headphones) included. Quite often, the banal reconnection of the speakers helps - if you have already tried all this and the problem with the sound has not been solved, then you can start reading the note.

Check the driver and your sound card

If you connected the speakers to the computer, but there is no sound ... then you will have to go to the device manager and see if everything is fine with the hardware and if we have sound drivers installed. Getting into the device manager is not difficult - open the "Start" menu, type "Device Manager" and press the Enter key on the keyboard.

The device manager will open. Expand the Sound, Game and Video Devices tab. Find in the list (if there are several) your audio device and double click on it to open its properties. Check the system message, the driver should be installed and the device should work properly.

Try updating the driver - this is done on the "Driver" tab. Quite often, a simple reinstallation of the device helps ... to do this, right-click on your audio device and click delete (but do not remove the driver itself - the system will ask you about it). After that, click the "Update hardware configuration" button at the top. This will reinstall the existing device driver.

Do not be surprised if you find yourself with several audio devices - this is normal. Almost all modern computers or laptops have an HDMI video output that can transmit sound and video over a single cable.

Choosing the correct default audio device

Open the "Control Panel", open the "Hardware and Sound" category. Select Sound. (why can’t you click on the icon next to the clock? - It’s simple, the interface has changed a bit in Windows 10 Spring Creator Updates and I will describe it below)

Here we are interested in the "Playback" tab and the list of devices. Consider an example - I have a laptop connected to an external monitor via HDMI. The monitor has its own built-in speakers... so you just need to tell Windows which device to use to play sound.

In the example below, as indicated by the green flag, we see that the sound is played through the monitor (only here the speakers on the monitor are reduced to zero! Therefore, there is no sound on the computer). You just need to choose standard speakers and sound problems will disappear.

It is possible that after choosing a different default audio device, you need to restart the programs, or even better, restart the computer for the new settings to take effect.

Windows 10 v1803 continues to nag The new look and feel of Windows 10 and the new version are affected by these changes to sound settings. In general, there is nothing difficult - right-click on the "Speakers" icon next to the clock and select "Open sound options"

Everything is the same here, just select the output (playback) device from the list and enjoy the sound on the computer.

Several sound devices will be active if you have connected your TV to your laptop or computer via HDMI… maybe you are using Bluetooth speakers and much more…

Turn off sound enhancements

In control panel (in the same place where you selected the default sound devices on the "Playback" tab) right-click on "Default playback device" and open its "Properties". On the Enhancements tab, select Disable all audio enhancements and check if the audio works.

If these manipulations helped - this is good news, disable sound effects for all your audio devices.

Check speaker or headphone connections

Almost all modern computers are equipped with at least three connectors, which must include:

1. Microphone jack
2. line input
3. line out

(exceptions are laptops, quite often they are combined and have only one dual-purpose connector - a microphone and a line-out). Make sure your speakers are connected to line out (usually colored green).

Maybe the advice is so-so, but you can try connecting to all the connectors in order to determine the one you need by typing

I would like to draw your attention to the fact that when you connect headphones on the front panel of the case of the system unit, the speakers will turn off - do not forget this nuance.

Misunderstandings with sound or dealing with HDMI

This problem certainly deserves a separate note, but I will try to tell in the context of our problem. If you have connected a TV via HDMI and are faced with a lack of sound on it, you need to delve a little into history.

If your computer and TV are brand new, then most likely you have the default playback device selected incorrectly, you can read above how to change it.

If your computer is no longer young, then it is quite possible that although there is an HDMI connector on your video card, it cannot transmit sound through this cable. In this case, either change the video card, or connect the sound to the TV with a separate cable (if possible).

In the control panel, open the properties of your default playback device and go to the "Advanced" tab. In the "Default Format" section, check each of the available ones in turn.

If it helps, save the settings and enjoy the sound on your computer. However, as practice has shown, this method helps very rarely.

If you are already desperate and have tried all possible options, then starting with Windows 8 there is an opportunity to automatically try to fix the problem with the lack of sound on the computer. Click on the speaker image in the taskbar and select "Troubleshoot audio"

Next, you need to select your playback device and follow the prompts ... if you look closely at the points, you can see that the system itself tries all the above methods and, if possible, combines them. Surprisingly, quite often this method helps, especially in cases where you have chosen the wrong device for sound output in the system.

Results

Well friends, in this guide I have described the most common problems with the lack of sound on the computer. In fact, there are many more reasons why there is no sound on a computer or laptop, but they are best considered privately. If these methods did not help you in any way, then please describe your problem in as much detail as possible in the comments - I will definitely answer and try to help you.

Computers have long ceased to be used exclusively for any calculations. Many people watch videos, listen to audio recordings and play various games on their PC. Sometimes, for various reasons, such a problem as “loss of sound” may appear. In this guide, we will look at the most common reasons why sound disappears and suggest ways to solve the problem. So what to do?

Causes

The disappearance of sound is usually caused by many factors that can be divided into two categories - these are hardware problems (headphones, speakers) or software problems. To begin with, consider the options for malfunctions from the first group.

Reason #1: Speakers, headphones, and other audio devices

One of the most common options is a breakdown of the speakers or a problem with their connection. To fix it, you need to check:

1. Is the device securely connected to the outlet;
2. Is its volume set to zero?

Also, if possible, you can check if the speakers work on another or any device to which they can be connected.

Reason 2: Sound card not working

Sometimes the cause of the loss of sound can be a banal malfunction of the sound card. But before replacing it, you will first need to eliminate all the problems in the software part, which will be discussed later.

Reason 3: System settings

Before looking for reasons in deep settings, you should check if the sound is muted in the Windows taskbar. This will require:

1. Click on the speaker icon in the system tray next to the clock.
2. A small window will open where you can adjust the volume, and you can also turn off the sound completely. If the speaker is crossed out, then click on it and the sound will appear.
3. It is also possible that the crossed circle is not displayed, but there is still no sound. In this case, check the volume control and turn it up.

Reason 4: Device drivers

The lack of sound may be caused by software problems that are responsible for its stable operation. It may malfunction or be completely absent. To fix this problem, you will need to download the drivers from the adapter manufacturer's website or, in the case of an integrated version, . After downloading, install them using the installer.

You can reinstall the driver in the following way:

1. Open the menu "Start" and go to .
   
2. Select in the new window.
   
3. After that click "Device Manager" .
   
4. You can also access this section directly by entering the command in the window "Run" , which is opened by pressing the keyboard combination Win+R .
   
5. Next, open the "Sound, video and gaming devices" .
6. A list will appear showing your sound card. By calling the context menu, you will need to select the item "Update Drivers..." .
7. Next, you will have two options - automatically search or install the driver from a specific location. If you have not downloaded the sound card software, then you can use the first option, otherwise select the second one and specify the location of the downloaded files.
   
8. In addition, the map in the dispatcher can be marked with an arrow. This means that it is disabled and you need to return it to working condition. To do this, right-click on it and select "Engage" .
   

If an exclamation mark is displayed next to the device name, the card is not functioning properly. You will need to do the following:

Windows will rediscover the card and configure it.

Reason #5: Service

Also, the reason for the lack of sound may be a disabled service that is responsible for its functioning. To run it you will need:

This section can also be accessed directly by entering the command services.msc out the window "Run" .

The service will start and the sound will appear.

Other causes and solutions

Another reason for the lack of sound may be a virus. In this case, manufacturers such as or Doctor Web will help. If none of the proposed methods helped, and you are sure that the reason for the lack of sound is not in the hardware of the computer, then you can try to roll back the system using a restore point.

And finally, of course, you can resort to using the most radical options, like replacing the card itself, but this should be done as a last resort if other options have not helped you.

A computer is a useful and reliable thing for work, entertainment and storage of documents. But even he can bring surprises over time.

Imagine the situation, the user turns on his laptop, but there is no familiar sound at startup. He starts listening to music, but there is still no sound. Most often, such problems are encountered with Windows XP, but this can also happen with new versions. What to do in this case? We will try to answer this question in the article.

Why there is no sound on the computer - reasons

There are several reasons for the sound to break on a computer. Some of them are not so terrible, and for some it is necessary to make an effort to fix the problem. So let's consider common causes of sound loss on a computer:

These are the most popular reasons why the sound on the computer disappears. Now we need to consider solutions.

Problem #1 Solution – Windows Volume Control

Sometimes the user himself turns off the sound on the computer, and then forgets about it. To make sure the sound is adjusted, you need to look at the sound icon on the computer panel. Click on it. The slider must be in the middle for the sound to work properly. If it's not, then just move it.

If there is no sound after that. That columns should be checked or headphones. To do this, make sure that the device is properly connected to the computer. Speakers must be inserted into the appropriate socket. The green button should be lit on the column itself.

Try disconnecting the speaker or headphones from the laptop and turning on the music, if there is sound, then the problem is not in the computer.

Check if the cable is connected correctly. Try unplugging and plugging in the cord again.

Helpful advice

How to restore the system? 1. Click on the “Start” button at the bottom right of the screen and select “Control Panel”. The main window of the Control Panel of the Windows7 operating system will open: 2. Click on the very first section “System and Security” and in the window that opens, select the subsection “Restore a previous state of the computer”.

"Eyes see, but ears hear ... how can they not hear!? Doctors here!"

Why on a working computer, completely working speakers can not reproduce sound?

Now let's look at the main reasons:

1. Sound card driver crashed.

You can check this through the Device Manager (in windows XP: Control Panel-Administration-Computer Management- select what you are looking for) In front of a device with damaged / missing drivers, a yellow circle with an exclamation mark will flaunt)

2. The speakers are connected to the microphone jack.

It's trite, funny, but sometimes it happens. Check.

3. Problems with the player

If everything is in order with the speakers themselves, the drivers for them, it may be the playback device. Install codecs or use KMP player.

4. Damaged connector.

Computers usually have two connectors where you can connect speakers, try all the options.

5. The system is muted.

Can be done two things:

first: go to the control panel-Sound, uncheck the "no sound" item;

second: in the lower right corner, double-click on the volume icon, in the menu that opens, make sure that all the sliders are in their maximum positions.

If the speakers reproduce some sounds, but refuse to “play” others, it’s definitely worth changing the player, updating the drivers.
