dapper + powerbook g4 = no sound?

[Matthew Nicholson]

just did an install of dapper on my powerbook g4, and, simply put,
everything went great. after a bit of hacking around the air port
extreme is working well and a few glitches i saw on a previous install
have cleared up.

however, currently, there is no sound. alsamixer/gnome-mixer have both
been used and the "normal" things are turned up. i even booted back into
OSX to make sure teh volume there wasn't set very low incase it was
hardware controlled. no dice.

any advice/help?
