gnome-media and pavucontrol could rely on PA to expose this
information (if/when available), sure. The difficult part is that
there is no consistency between MicX - it's really up to the mainboard
provider.

PA has begun to move a lot of the insane logic into config files, but
I'm not comfortable relying on that approach (which really relies on
alsa-driver/linux to expose the IDs via /proc/asound/card*/codec* for
HDA) due to how volatile things are...
