I want to use Elementary os 5.1.7. But the microphone is not working on it. No sound is detected and the bar of the "input level" does not move at all even if I am speaking something. I tried reloading alsa, and everything seems to be alright in alsamixer too.

What can I do?

Some background :

  • Hardware: Acer Swift 3 (SF314-55G), i5 8th gen(8265-U)
  • Currently, I am using Ubuntu 20.04- sound works okayish here. I have to switch the output source manually everytime I connect external wired headphones. And the internal microphone works, but the external headphone mic does not.
