Power Mac G4 Sound Support on Potato r0 ?

[bda@free.fr]

Hi everybody,

I'd like to know where i can find documentation for the sound support on Power 
Mac G4 with the potato 2.2 r0.

During the installation process, i have load the sound-core module on my kernel 
(2.2.17 for this moment) and i have no sound (no gnome's sound, no sound when i 
play an audio CD) but when i type 'lsmod' i can see the sound core module and 
it is used, but by what ?

I have another problem, when i launch some gnome's programs, i have some 
messages who tells me "/dev/dsp......", anyone can explain me what is /dev/dsp ?

Thanks for your answers.
