Attempting on a ubuntu live-usb I found the mic working. I ran the info script for both OS's (see below). My interpretation of the info dumped by the script is that ubuntu loads the `sof-audio-pci` drivers and arch linux seems to load some other intel drivers. Looking through the [arch wiki](https://wiki.archlinux.org/title/Advanced_Linux_Sound_Architecture#ALSA_firmware) I see reference to some newer laptops requiring the sof drivers:

try with this option removed: "options snd_hda_intel dmic_detect=0"

It's old stuff that should have been removed by the distro.
