According to:
https://help.ubuntu.com/community/MacBook6-1/Lucid

Sound works out of the box, BUT you must enable the spdif and surround from the alsamixer, also turn up all the volume controls.

Open a terminal window and type alsamixer, then with the arrow keys turn up all the volume controls and activate the surround and spdif with the colon and dot keys.

Thanks that worked great :)

I also noticed that the front speaker and surround speaker were at minimum. I used '+' to increase the volume.
