Lost sound?

Question

Iron

For no poor reason, the sound disappeared. The only manipulation was with iron, I took out a vidyahu to clean it. The front and back panels are silent, the driver is standing (deleted, reinstalled, removed devices from the manager, etc.) There is sound via HDMI (there is an audio output on the monitor, if you poke headphones there and set the device by default, then everything is OK), but not from the chipset (although there is an indication of activity). How to be? what to do? ALC89x

Answer 1

The fact is that you may have damaged the circuit element of the built-in sound card while manipulating the video card - very close to the video connector (PCI Express bus) there is a harness for the built-in sound card. In order for a sound card to fail, sometimes a static discharge in the "right place" accumulated in dry air conditions from the operation of central heating on the surface of your body is enough, not to mention the possibly careless movement of a screwdriver along the surface of the motherboard.
If we assume that the AUDIO circuit remains intact, then it is necessary:
I do not advise repairing. diagnostics, repairs, etc. will draw more money, time and effort than buying a new entry-level discrete card.

Answer 2

Have you tried setting the audio output? Look at the system mixer, maybe mute is there.

Answer 3

Did you run a Linux distribution on a computer?

Answer 4

I have the same situation, I also pulled out a vidyahu.
The only thing is that I still hear some clicks from time to time in my right or left ear.
It was probably not possible to diagnose a hardware problem, since there is no way to play sound in Windows PE.
