[MSI MS-7B98] Sound is faster, high-pitched and distorted

[Michal Lašan]

It works normally when playing youtube videos, only audio files on PC are a problem.
Also, kernel 5.8.0-50-generic does not have this problem.

Since you say the current kernel for Ubuntu 20.04 does not have the problem then it is considered Fix Released.

If there is a newer kernel that does still have the bug then you should report it upstream, not here.
