Hi FA and everyone else that was helping,

I just got the mic to work by installing pipewire. FA, I think you are right because when I installed pipewire and checked pavucontrol, I can see that the mic selected now is dmic. When I try arecord with `-D hw:0,6`, though, I get an error "arecord set_params:1396: Channels count non available".

To summarise, what I did was to install sof-firmware and then install pipewire and reboot the machine. Thanks to everyone here and irc!
