alsa-project/alsa-ucm-conf pull request #310 was edited from BearsPunch: When I installed Manjaro I had issue that my audio card was not recognized. USB ID is 0414:a00d and as I see you already have it under if.realtek-alc1220-vb condition, but I have ALC4080. So I manually changed USB-Audio.conf under If.realtek-alc4080 condition from (0414:a0(0e|1[0124])) to (0414:a0(0[de]|1[0124])) and now it works perfectly. But Ubuntu (maybe from 22.04) doesn't have this issue. Does Canonical update alsa-ucm-conf by themselves without pull request to main branch?
