Ah, right. I'll have to check with Ben a bit more when he comes back. He
seemed to have half of a plan ;)

Yeah, I guess, but that's only doable with the tas codec. I don't think
it's hard, if anyone wnats to try: the tas datasheet is in my
repository, and all you need to do is modify the tas codec to show the
controls for that. Could also use some bass/treble controls.

If we want DRC even for the other machines, that's an alsa userspace
thing since it needs a soft-DSP then.
