Comment 113 for bug 1801540

Hi Marco,

Just to back it up, I tried the same things and I'm in the same situation:
ALC1220, [1022:1457] subsys [1458:a0c3] on 5.1.7.

Explored and played around with the snd_hda_intel, especially around
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/hda_intel.c
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/patch_realtek.c

Tried different quirks, including the Gigabyte ones ( dual codec etc. ), with NO LUCK. Explored also with hda_analyzer and played around with the components but not useful.
Wanted to get in contact with tiwai to understand better the module parts, but then i read your comments informing also that it was about the codec part and docs/specs missing from AMD so didn't continue the effort.

Would be interesting to understand if the problem is really about the codec ( feels like ) and who could be contacted to obtain missing info... shouldn't it be realtek related?
