I lost sound on my computer. The problem appeared when I pulled out the BIOS battery. At first, the speakers began to hum when I watched a movie and listened to music. They hummed softly, then became louder, and the sound disappeared altogether. I again pulled out the BIOS battery, the sound appeared, but with a hum. The next day I turned on the computer, there was no sound. I don’t know what to do, nothing helped.
Why did you remove the BIOS battery?
If there are problems with the playback of music files or the speakers began to emit extraneous sounds, 'tablet' B IOS is in no way the cause and any solution.
If the speakers are buzzing, the first thing to do is connect them to another device, and if they keep buzzing, then the reason is in their physical malfunction. Also note that speakers may react to external sources of interference, such as a phone lying next to them.
If they work stably, then the reason lies directly in the computer:
1. The drivers for the sound card are not working correctly.
2. The sound card is physically defective.
3. Poor contact with the connection socket.
4. Influence of external connected peripherals.
Check for these reasons, and also note the existing integrated ways to check the correctness of the sound that are in the operating system Windows.
