iMac 24" (Aluminum unibody)
No Sound (Ubuntu 10.04)
Out of box, sound won't be coming out of the speakers, regardless of how much meddling you attempt in alsamixer. Here's the audio device and driver in use:
oem@freekbox:~$ lspci -k | grep -i -A2 audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
In order to fix this, create a file under /etc/modprobe.d/options and enter the following:
options snd-hda-intel model=imac24
and reboot the system. Prepare to be blown away by Ubuntu's awful drum sound.
