No sound on Macbook under Ubuntu 10.10

Asked by Daniel Huxman

I installed Ubuntu on my Macbook alongside my OS X installation. Under Ubuntu however, I only get sound when I am not using speakers. Also, a red light is on in my speaker port. I believe that Ubuntu is looking for optical audio for some reason. How can I make it use speakers normally?

Aha! I fixed it. I discovered the gnome alsa mixer and unmuted it. Also found a way to turn off the light (turn off IEC958). Sorry, Linux noob here. :)
