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. -- :wq
