Hi
In downstream Debian we got a report from Eric Degenetais, in https://bugs.debian.org/1081833 that after the update to the 6.1.106 based version, there were regular cracks in HDMI sound during playback.
Eric was able to bisec the issue down to 92afcc310038ebe5d66c689bb0bf418f5451201c in the v6.1.y series which got applied in 6.1.104.
Cf. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1081833#47

It should be noted that Eric as well tried more recent stable series as well, in particular did test as well 6.10.6 based version back on 20th september, and the issue was reproducible there as well.
Is there anything else we can try to provide?
Could you check 6.12-rc1 kernel whether the problem still appears? If yes, check with snd_hda_intel.snoop=0 boot option.
I guess we should revert the patch in anyway; for 6.12, it's no longer correct to check with get_dma_ops(), and if this causes a problem on the older releases, the assumption isn't correct, either.
thanks,
