Public bug reported:

Upon installation of Ubuntu 8.10, sound can be enabled by adding
"options snd_hda_intel model=mbp3" 
to /etc/modprobe.d/options
(This is needed due to a detection issue, but that is another bug)
After rebooting, the sound does work, but there is no sound from the Macbook's built-in subwoofer which makes the sound very poor sounding in comparison to how it sounds in OSX. This difference puts Ubuntu in a bad light. Users often complain about "tinny" or "poor quality" sound.

This is specifically occurring on Macbook4,1 models (and likely
Macbook3,1 as well)
