I'm running latest HWE kernel on 20.04 (5.4.0-65).
If I connect a microphone via USB or the headphone socket then it works (in chromium too).
But if I disconnect the microphone then Gnome doesn't detect any built-in microphone.
As I've made some changes to my modules settings, I think I'll wipe the system and try it with a fresh install.
