I have the same problem after installing windows 11
Installing drivers from the official website of the motherboard does not help, google and thousands of pages with options to solve the problem - also did not help.
Hello!
Motherboard: ASRock H310M (https://www.asrock.com/mb/Intel/H310M-HDV/index.ru.asp)
With Realtek ALC887 sound
I had windows 10 for several years and the sound worked fine.
I decided to upgrade to windows 11.
After the upgrade I had a problem with the sound - the sound is gone...
