It seems this bug doesn't apply to me, and that I just needed to find the right
documentation, then set the model= parameter. Sorry for the waste of time.
I'll note my solution in case it helps random web searchers, but it's NOT
related to this bug. I should also qualify these hints: I just found something
that worked for me and don't deeply understand what is going on.
I set the option in a new file (/etc/modprobe.d/alsa-hda-intel-model.conf):
options snd-hda-intel model=6stack-dig
(the first one I tried worked with my headphones, that's all I need)
I applied the change with:
$ sudo alsa force-reload # BEWARE kills you're audio using processes
$ cat /sys/module/snd_hda_intel/parameters/model
This fixed the stutters/crackles at high volume for via both alsa and pulse.
