Yeah, the intel_hda system is pretty funky. My understanding is that
the API is essentially a programmable plugboard connecting the various
DSPs on the chip, and that the "codec" is a mapping of which pins
connect to which.

Kinda neat, actually. You'd think someone clever would try expressing
that interface more intuitively to the user.
