Could you check the very latest Linus tree (6.0-rc5)? There has been a regression fix for HD-audio, and possibly this might be your case.
And if this doesn't change the behavior, try snoop=0 option for snd-hda-intel module.
Thanks, I've just tried with 6.0-rc6 both with and without snoop=0 and neither helps I'm afraid.
Then one another thing could be position_fix option of snd-hda-intel. Otherwise we need bisection -- supposing it worked well in the past.
Thanks, position_fix=1 does the trick (I did not try any of the other possible values).
I see there is a snd_pci_quirk position_fix_list, so I guess I should prepare a patch adding a quirk for this?
I guess this is rather controller issue, so I'd patch for Poulsbo like below. Let me know if it works, then I'll cook a proper patch.
Or are some other position_fix values preferred and should I try those first?
LPIB should suffice, so no further test about the option needed.
thanks,
Takashi

I can confirm that this does the trick, thanks:
