Hi and thanks. I know about mpd, it's on my list of things to try if I
can run FreeBSD on the Pi 4B.

I wasn't talking about audio over USB at all but rather using a "HAT"
as far as I have seen them called, that plugs into the GPIO ports as
you mentioned. The output I'm looking for is S/PDIF coax or AES/EBU.

Bypassing USB is usually a better audio interface if you have an alternative.

Thanks.
