Thanks Dustin and Kieran. This approach makes sense to me then.

I don't believe so - the audio expansion card enumerates as a USB
device that is picked up by snd-usb-audio.
A headset microphone connected to the audio expansion card seems to

tested on my Framework Laptop 13, mind you -- it is not a perfect test
:)).
