Hi everyone, I have just tried Karmic Koala on the same iMac model
mentioned here (9,1 March 2009; 20"). For me, the internal speakers and
headphone jack do not work. I don't know about the mic, as I have tested
in a Live environment and therefore could not install Audacity to check.
If I type in aplay -l, the output is the same as in the bug description,
except the sound card being ALC889A? Is this some kind of revision?

Anyway, should I continue to install regardless of sound? It seems a
daunting task to fix the problem in my opinion.

Bug description:
I got a new iMac, (version 9,1 March 09). Everything works perfectly except the sound. Sound comes out of the headphone jack. Sound does not come out of the speakers. I've tried numerous fixes, but I think it comes down to the newest iMac hardware not being supported yet.
