What if the computer has no sound?



Check the sound card driver






1. Check if the sound of the system tray is closed or not.

2. If you don't have one, you can go to the driver settings to see if it is set to mute.

3. If you still don't have one, you can check if the computer system is damaged and the driver is normal.

4. If there is no problem, you can check if the sound card is damaged.

5. If there is no damage, you can check if the speaker is damaged.

The computer cannot play sounds, usually caused by volume setting problems, audio service abnormalities or playback device problems. Solution:

1. Adjust system volume settings : Click Start - Control Panel - Sound - Play, double-click Speaker - Level, move the Audio output slider to the far right, and then view the sliding of the Rear and Front items (ie the front and rear panel audio items) Whether the block is already at the far right. If the volume is set properly, go back to the playlist to see if there is a device with the same speaker comment. If there is such a device, you need to right-click to "deactivate" the device.






2, use the 360 ​​program to repair the audio service: open the security guard - manual service, enter "computer no sound" in the search bar above and find Solution, then find the corresponding solution in the search results list and click "Repair Now" on the right side, you need to restart the computer after the repair.






3. If the system settings and sound card drivers have been fixed, it is a problem with the playback device: first pull out the audio connection of the speaker or headphones. Plug in the Mobile
or TV to test whether the sound is playing normally. If you can't hear the sound after inserting other devices, the player itself is faulty; if you can hear the sound, it is a computer audio socket problem, you can replace the socket and insert it (the front panel of the main unit has an audio jack).
