Re: AW: Sound on an iBook?

Hi All,

(Michael, this might not make to you... because of the dreaded ORBS
situation - which *still* hasn't been resolved after 4 months).

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.

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.

There was a guy working on the iBook sound (which was why I'd left it alone
for now).  He said that it only took a couple of lines to get sound out...
although I suspect you'll have to rely on whatever settings MacOS last left
for it.... because...

The "problem" is that the mixer abstraction needs a re-write to talk to the
Micronas chip.

I've been (very) out of circulation and will be until Xmas or so... but if I
have a chance I'll see if I can find the relevant lines (IIRC it only
involves detecting the iBook in init and dealing with the register
assignments... but it's been a while since I looked).

Iain.
