Ah.

Up to now only built-in speakers. Will try with headphones :)

I tried in the Gnome Sound Settings. And I tried Sin naturally :) (Sound
works on Linux-x86, and does not contain any x86-specific code, so normally
it should work on LinuxPPC straight away - if sound is correctly configured,
that is :) )

Well, I have some sound programs here... at least the Sin-stuff should work...
quite straight WAV-replaying...
