It might help to have the mixers and muxes maintain some state when they
change?  It's just a suggestion, I'm not familiar enough with the codec
to know if it's a sensible one for this device or if it's more trouble
than it's worth.

Ah, right.  Possibly worth making it platform data, I suppose, but
that'd be a pain when experimenting to find the values.
