Here's what I got:

Unloading ALSA sound driver modules: snd-powermac snd-aoa-i2sbus
snd-pcm-oss snd-mixer-oss snd-pcm snd-timer snd-page-alloc

I'm not sure if it's relevant, but my machine is quite old (G4  
Powermac (Quicksilver)). Is it possible that the
aoa-tas driver isn't recognizing it because my card is too old?
