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`
