How to fix sound on a laptop?

Question

Windows

Yesterday everything worked, today I woke up - it no longer works.
Everything points to the fact that the sound is there, but it is not.

Driver reinstalled.
The last update of the system was half a month ago (yesterday the sound worked).

Answer 1

Lord, where do such questions come from ...
Turn on your head!
1) Checking the software. If the rearrangement of firewood did not help, then load the LIVECD, check with a clean system.
2) Check the iron. We change mother, sound.
