Hmm, so they're not overly helpful here. Probably some custom-made chip.

This is more interesting though - too bad I don't have the hardware ;)

Ok, that's the same as in my iBook, but there it's called 'deq' so
that's why it doesn't attach. More code to change.
One last thing - what's the 'compatible' property of mac-io/i2s ? The
current driver only knows about 'snapper', maybe they're similar enough.
At least both use the same codec/mixer/equalizer chip ( Texas
Instruments TAS3004 )

Thanks for looking it up.

have fun
Michael
