Re: [debian-powerpc] New Ibook no sound , Works only for the headphones
Being a mac-owner for only 48 hours now, I don't really understand too much of
the hardware-side of my iBook. So, I might be misunderstanding some of your
questions, but I'll try and give my best in answering them. :-)

No, it was detected as an awacs-card. That's also what hwinfo tells me.

This doesn't really mean anything to me.

Sure, here it is:

Sorry, I don't have that file.

Okay, here we go:

Well, I don't really have a clue why that patch works, so I don't like to
submit it to mainline before I have some deeper understanding of what I
actually did... ;-) So, I will submit it as soon as someone with more
knowledge of apple's sound-hardware confirms that the patch looks reasonable.
