Hello,
I got no answer on the debian-ppc list, so I'll try here.
does anybody know a way to get the sound hardware on my iBook working?
Everything else is working fine.
The iBook has a different Hardware than all other Macs found so far.
There is an (unsupported, ugly ...) version of dmasound that
sometimes works on iBooks, but it provides no control of the
output, it just takes what OF or MacOS left behind. So using
such a Kernel/Module is a kind of russian roulette because it
will block forever when intializing fails.
This issue needs a good assembler-/Forth- Programmer that must
use MacsBug in MacOS or dissassemble the OF to find out whats
going on there. I'd really like to do that but that is nothing
I can do when going to work by train ....

Christof could always resort to petitioning Apple to release the specs, or
digging though Darwin source code to discover the secret.

Well, the DACA chip itself seem to be a non-Apple thing, so doc
for it may be available. The issue is more to have an i2c driver
for KeyLargo.
I don't think hacking the forth code is the easiest solution for
that ;) It's probably a lot simpler to look at Darwin driver to
figure out how the chip works ;)

Yes, this validates my suspicions.
There is an (unsupported, ugly ...) version of dmasound that
sometimes works on iBooks, but it provides no control of the
output,
read: no volume control, no frequency change? That is not nice but
acceptable.

I would love/dare to try it.

Oh no, that sounds really bad. No specs available, no darwin driver?

Hmm. It reads like a joke. But I love to work on my computer in a train.
I would offer some time but I don't know any PPC assembly. C and
Linux-kernel are no strangers to me.
