Comment 22 for bug 346170

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.
