Both internal and external mic don't work

Please read this:

Especially the Linux has multiple kernels section, then try an LTS kernel and hopefully the problem will go away “automagically”. :grin:

If that doesn’t help, try disabling PipeWire and running on PulseAudio only:

systemctl --user disable --now pipewire.socket && systemctl --user disable --now pipewire.service && systemctl --user mask pipewire.socket
