No Micrphone detected on ALC4080 - Gigabyte B850I Aorus Pro (rev 1.0) - Alsa-devel - mailman.alsa-project.org

19 Mar 2025

      alsa-project/alsa-ucm-conf issue #528 was edited from chanster:

The Rear Microphone is not detected when I plug in my mic. I don't use the Front Audio connection as my case doesn't have I/O for it, I just used the 2 audio ports in the rear.

When I try recording directly I can get the mic to work, but it does not show up in the sound settings.

`arecord --duration=3 -D hw:CARD=2,DEV=1 -f dat -vvv a.wav`
