Hi,

I have a rather interesting issue on HP EliteBook 1040, with Intel ADL
HDA. Sometimes (often) audio output is heavily distorted, but then
opening pavucontrol or just launching `parecord /dev/null` fixes the issue
instantly. But, when the mixer or recording is closed, then few seconds
later issue comes back.

You can hear this at https://cloud.marmarek.net/s/46prqZnwrqDkBdD
Initially recording was running, then about 10s stopped and you can
hear the issue few seconds later. Then I starter recording again, and
the issue is gone.
This is how it should sound: https://youtube.com/watch?v=4Tr0otuiQuU
I do not see any kernel messages when issue happens.

The issue happens on Linux 6.1.26, 6.2.10, and 6.3.2. I haven't tested
other versions. It happens only when running under Xen (in PV dom0). The
very same Linux started directly works fine. Full dmesg of both native
and Xen boots is at https://gist.github.com/marmarek/548ee79282446344a172109bcd943930

When running Linux 6.3.2 there, I noticed that just after boot first
playback is okay, but if I start and stop recording it breaks. And then
after some time of idle it fixes itself again. I have not observed this
behavior on 6.2.10 (it was broken initially too), but I could be also
doing some things differently. 

I have few other ADL-based systems (but not HP), and they do not show
this issue, only this HP laptop is affected. Example dmesg from another
ADL-based system:
https://gist.github.com/marmarek/38c5ba3ec58f9300fbc1842ddc9fa4f5

I'm not sure if that's the relevant difference, but comparing dmesg from
working and not working systems, I see those on boot for the
problematic case:
