Public bug reported:
This bug is a regression when upgrading from precise to quantal.
The sound sounds works okay on my Mac with kernel 3.2.0-27, but there is
no sound at all if I choose a 3.5.0-7 kernel, all other packages and
all settings being exactly the same. This seems to prove that the
problem lies within the kernel.
In case it helps, in /etc/modprobe.d/alsa-base.conf, I have "options
snd-hda-intel model=imac91".
