The iBook has only recently gained sound support - the driver in 2.2.15
doesn't support it :/ Neither, for that matter, is there any support in
the rsync trees on penguinppc.org (bitkeeper.fsmlabs.com rsync is down).
However, it seems the only place that has the iBook-capable driver is
at http://students.washington.edu/mpalczew/ - the dmasound.c.gz arc at
the bottom.
How the support has been done looks fairly simple (fwics). The G3 PowerBooks
have a bus called "davbus" with a member "sound". Similarly, the iBook has
a bus called "i2s-a" with a member "sound". It looks like the reason this
hasn't been synced into the main tree is because the support for iBook
sound removes the support for PowerBook G3 sound.

They don't for me - I'd be interested to see your patch ;)
