Reason 1: error in sound card driver

The main reasons: the sound card driver is disabled, the sound card driver is damaged, or the installation of unsupported device drivers are the main reasons for the loss of sound on the computer.

Solution: click device Manager in the Control Panel to see if there is an "X" on the small speaker in the sound card item in the sound, video and game controller, where the sound card is disabled. Select the sound card item and press the enable button on the toolbar. If "sound, video and game controller" is preceded by "!" Or "?" Which means that the sound card driver is damaged, just reinstall the sound card driver

Reason 2: the volume is not turned on

The main reason: everyone should know that the volume can be adjusted through the "trumpet" in the lower right corner of the desktop. If you set the volume to mute, or keep it to a minimum, the computer will have no sound.

Solution: click the horn icon in the lower right corner of the system, first confirm whether the volume is turned on, and adjust the sound to the appropriate volume. If the "small speaker" icon in the lower right corner is also missing, go to the "Control Panel", double-click the "Sound and Audio Devices" item, in the pop-up "Sound and Audio device Properties" window, select "Volume" page, then adjust the volume adjustment slider to the appropriate position, and hit the hook before "put the volume adjustment icon into the taskbar", confirm and exit.

Reason 3: the speaker cable is not connected properly.

The main reason: there are many jacks on the mainframe of the computer, so that people don't know which Jack to plug the speaker cable into. If you don't pay attention to it, you may plug it incorrectly. If the speaker cable is not plugged into the corresponding Jack, the volume of the speaker is placed in the lowest position or the speaker has no power supply, there will be no sound on the computer.

Solution: first, turn on the stereo switch and turn the volume up. If there is no sound, take a look at the back of the computer mainframe. The audio output at the back usually has three ports, red, green and blue, red is the Mike, green is the stereo, blue is the output, and the audio cord is colored. Just insert the Jack of the same color. After plugging in, try to turn on the volume. See if there's a sound.

Reason 4: viruses in computers

The main reason: if the virus in the computer damages the files related to audio processing, especially the system components related to Dsound, it is likely to cause the computer to have no sound.

Solution: use antivirus software to check whether the computer has a virus, kill it quickly if there is a virus, and eliminate it completely. if the virus is too stubborn to be completely cleared, you can restore or reinstall the system with one click.

If all the methods provided above have been tried and the computer still has no sound, it is likely to be a hardware problem, and it is best to find professional maintenance personnel to repair it.
