How to fix a problem with sound on a computer

If you are faced with a lack of sound on the computer, do not rush to immediately run to the service center, in most cases it is not difficult to fix the situation yourself. Problems with sound on a computer can be divided into two parts.

1. Hardware malfunctions:

failure or improper connection of speakers and headphones;
audio card malfunction;
damage to the electronic components of the motherboard;
Crash in BIOS firmware.
2. Software failures:

problems with drivers;
lack of necessary codecs for playing some types of files;
improper hardware configuration by operating system tools;
viral infection.
How to start troubleshooting a sound problem on a computer?
Before you begin to test or configure the sound card, click on the speaker icon, which is located in the notification area of ​​the taskbar. Make sure that the volume is not reduced to a minimum.

Check if the sound devices are connected correctly. Make sure that the switch on the speakers themselves is in the “On” position and that the plug is plugged into an electrical outlet. Ensure the integrity of the wires. Check if the device is working on another computer or laptop.

Right-click the speaker icon again. Select Playback Devices. In the window that opens, you should see your speakers (or headphones) marked with a green tick. If they do not appear, click on an empty spot in the window box. In the menu that appears, check “Show disconnected devices” and “Show disconnected devices”. Right-click on the appeared devices and click “Enable”. Confirm the action with the “Apply” and OK buttons.

Remember your last steps on the computer. If you installed a new program or were involved in cleaning and tuning the operating system, the restore function can help. To start the procedure, open the “Control Panel” and go to the “Recovery” section. Click the “Start System Restore” button. In the dialog box that opens, click Next. The recovery point should be selected at the moment when the sound was playing normally.

Installing codecs for playing music
If problems with sound on the computer appear while playing music or video files, the reason is the lack of the necessary codecs. The easiest solution to this problem is to install a free K-Lite Codec Pack on your computer. You can download it from the official website of the manufacturer. Before installation, it is recommended to close all running programs. Be careful: installing codecs downloaded from unverified sources can infect your computer.

Scan your computer for viruses
Verify that the antivirus database is up to date. Run a full virus scan and wait for the results. If the antivirus program detects an infection, agree to the proposed actions. In addition to the standard anti-virus program, you can use the free utilities offered by the developers. The best of them are Dr.Web LiveDisk and Kaspersky Security Scan. Please note that before checking, you must download the latest version of the application from the manufacturer’s website.

How to update sound card drivers
Open the “Control Panel” and select the “Device Manager” section. Find “Sound, video and gaming devices” in the equipment list. Right-click on the audio card and click on the “Update Driver” button. It is recommended that you select automatic updates. But you can manually indicate to the system the CD with the drivers included in the kit when purchasing the card or the driver downloaded from the Internet and saved on the hard disk.

How to properly install the driver on a sound card
If there is no sound on the computer at all or is jerky, a problem with the sound on the computer is caused by the lack of drivers.

First of all, you need to determine which audio card you have installed. Go to the “Device Manager”. Highlight a line with an audio card. Right-click and select Properties. Go to the “Information” section and in the scrolling list click on the item “Equipment ID”. Copy the contents of this line.

Go to http://devid.info/ru/. Paste the copied code into the search box and click Search. In a few minutes you will receive information about your sound card and archives with drivers. Select the latest driver that matches your operating system. Download the archive and unzip it. Run the installer. If the audio card is working, then the sound should appear.

You can also determine the model of the sound card on the website http://www.pcidatabase.com/. To get information about the device on this resource, you need to enter the values ​​VEN (manufacturer) and DEV (device). Both parameters are indicated in the copied code. Having determined the model of the card, go to the official website of the manufacturer and download the latest drivers.

In addition, you can use special programs to determine the installed equipment.
