Sound
If you have an aluminum iMac and you do not have sound :
open /etc/modprobe.d/options :
sudo nano /etc/modprobe.d/options
and add "options snd-hda-intel model=imac24" to the file and save ( ctrl+o and ctrl+x to exit )
then reboot.
Eläimen.Varmuus: With Ubuntu 8.10 (amd 64) and iMac rev. early 2008 the first step was enough. I edited only /etc/modprobe.d/options.
Some of the Aluminum iMacs need a patch to get functioning sound. An ubuntuforums user, 'nicfagn' has created many patches and posted them in the forums. Many of the fixes have made it into the latest ALSA driver, so downloading and compiling the latest ALSA source code may work as well. Here is a link to a patch that many have found useful.
Tiziano Faion: If you have an Aluminium Imac setting in /etc/modprobe.d/alsa-base the option model=mbp3 make sound work without patching anything.
Schijnt alleen bij aluminimum imacs nodig te zijn, geen idee wat dat is, kleur waarschijnlijk, rare jongens....
