My Lenovo x1 Gen4 has an Intel "Sunrise Point-LP HD Audio" and I'm trying to record audio through the onboard mic.
In Alsa "List all PCMs" (arecord -L) show many different PCM's (for my one sound card). Selecting a certaine one ("plughw:CARD=PCH,DEV=0") in arecord works, the other PCM's do not work.
So I'm either looking for a way to change the default pcm to plughw, or to have Pulseaudio pick my working alsa PCM.
This answer seems to come close to what I need, but in playback rather than recording.
Anything I can try or hints in the right direction are most welcome, thanks in advance!
