Well, for quite some time (though original on ibook).

Additionally installing mpg123-alsa does not help at all. And trying
with (self-compiled) mplayer does not help either. I think I tried
various other players. Do you have /dev/dsp?

With strace, I see that my mpg123 tries that device (file) as well, but 
it is not present. In /dev/snd I only see controlC0 and timer. And
yes, snd_aoa_fabric_layout is loaded (among other sound modules).

I think I'll have to hunt now why I don't have this device.
