Line & Mic In detected, but not working on MPG B650I EDGE WIFI (0db0:36e7)

9 Jan 2024


      alsa-project/alsa-ucm-conf issue #281 was reopened from 13r0ck:
Seems to have been broken by 33b934c29d2911ef060d48b1a0ca9682645b68c8 , as it was completely functional in 1.2.7.2
I did manage to find a patch that fixes the line in on 1.2.8:
  All it does is disable spdif for that usb id.

But I am struggling to find what is missing to make mic work. Jack detection is fine, and I can get recordings via `arecord`, but I am missing something with the ucm conf.
