Audio on my daily driver #OnePlus6 running #postmarketOS has had a major regression this week (maybe hardware problem?) and now I think I need to buy a different phone.
And here's my documentation of the fix: https://gitlab.com/postmarketOS/pmaports/-/issues/2466#note_1756841067
I managed to prove the HW is working thanks to some things here https://wiki.postmarketos.org/wiki/Alsa_UCM
So I guess just the #alsaUCM config is wrong for my oneplus 6.
