Internal microphone problem -- No Recording Devices Available

[papapenguin]

I use Kubuntu and the KXStudio repository for my laptop. I'm able to record just fine using JACK and an external USB preamp (Focusrite 2i2, Tascam US-122L) but my internal microphone doesn't show up in the Audio settings. I see the microphone in ALSA mixer, and the internal camera automatically works in programs such as Skype or Zoom, but the microphone doesn't.

Any ideas?

Hi everyone
I have the same problem.
My micro was working fine but after one of the last updates it stopped working.

I'm noob. Can you help me please?
