Subject: Regression in v5.19-rc4 Sound Distortion

Hi everyone,

(please keep me CC as I am currently not subscribed to LKML)

Since  v5.19-rc4 this box got some *loud* distorting sound on boot and 
after some time without any sound if something plays sound again from 
the integrated speakers in my monitor.

I managed to bisect this down to:

> commit 202773260023b56e868d09d13d3a417028f1ff5b
> Author: Dmitry Osipenko <dmitry.osipenko@...labora.com>

Reverting that commit on top of v5.19-rc6 does indeed fix the problem here.

Any ideas?

Greetings,

Daniel
