This is on a Performa 6400.

The source is from Paul's developent tree.

I've compiled sound support in rather than as a module.  It works, but
the only way to control the volume is by using the Gnome mixer.  On
anything else I've tried (xmms, the CD player that comes with Gnome,
reaplayer), the volume sliders don't work.  But the sound is fine.
