Internal Microphone Not Detected

local_buffoon · 2025-11-04 02:54:41

Mic was working fine until yesterday during a zoom call. Audio seemed to randomly switch to "Cannon Point-LP High-Definition Audio Controller" for the first time, which I don't recognize. Working on a Thinkpad T490 and I swear it was RealTek this whole time, but I could be hallucinating. Unsure if that's related, but it's when I noticed the mic not working. Settings indicates "No Input Devices" on audio input. Additionally, the indicator light on the F4 key which toggles the microphone quit working.

hardware:

# arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

When I run

 arecord -vv --format=dat /dev/null

I can see that it detects sound, so the microphone is at least working.

Volumes are up and capture is on in alsamixer capture view as well.

All help welcome, thanks!

Does

arecord -Dhw:0 tmpRecording.wav

work? Technically the mic is there, even from a pulse perspective but marked as "unavailable" if it randomly happened during runtime, did you update the kernel or any audio related packages when doing so?

local_buffoon · 2025-11-07 00:45:46

I get

 $ arecord -Dhw:0 tmpRecording.wav
Warning: Some sources (like microphones) may produce inaudible results
         with 8-bit sampling. Use '-f' argument to increase resolution
         e.g. '-f S16_LE'.
arecord: set_params:1387: Sample format non available
Available formats:
- S16_LE
- S24_LE

I haven't updated either zoom (where I first noticed the issue) or any other packages dealing with the microphone at least. The only audio-related activity I've had recently is messing with mplayer to get sound to work on HDMI.
