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!

  • PulseAudio ignores most of the ALSA configuration; the default device must be set in, e.g., pavucontrol.

  • Thanks for your feedback. In pavucontrol the input device is not shown. ("No input devices available") I'm completely out of my depth I'm afraid. Anything I can do/try/read?
