HP 840 G6 microphone issues


Does anyone have a laptop HP 840 G6 (standard from CERN store)?
Centos8 does not recognize built-in microphone. Googling does not help much.
Anyone has ideas?

Hi, I have that laptop and I am using Fedora 32 on it. The microphone works fine for me. Do you use pulseaudio or alsa or …?

After many unsuccessful attempts to get mic working I gave up and reinstalled OS to Ubuntu 20.04. Mic is working now.
