Hello Sakamoto-San, I came around to testing your patch [1], after RFT.
I've had to make the following changes to patch 1/5 again for it to apply to
mainline (d1f2d51b711a3b7f1ae1b46701c769c1d580fa7f), due to missing b171e20
from 2009 and a7ecbe9 from 2022.

Then everything applied fine.
This resulted in 6.11.0-rc6-1-mainline-00326-gd1f2d51b711a-dirty.
Testing it with TI XIO2213B and RME Fireface 800 so far:
Initially I had a buffer freeze after 3 hours of continuous ALSA playback
from mpv:
mpv --audio-device=alsa/sysdefault:CARD=Fireface800 Spor-Ignition.flac
accompanied by stresstest (mprime).
It didn't freeze/crash the kernel, just the audio buffer kept repeating.
Gone after power-cycling the interface and restarting playback.
Can't say with certainty whether it's related, have been unable to replicate
the issue for the past 3 days (good sign I hope).
That's why I was holding this message back a bit.
Kind regards,
Edmund Raile.
