I have seen similar errors from artsd - it appparently doesn't wish to
obey the sound driver's request that it use a different (in this case,
big-endian) sample format. Someone should rattle the aRts developers'
cages over this.

I haven't tried VLC on anything, so I don't know about this. The
developers of VideoLan, however, probably aren't making their client obey
the driver's request for big-endian samples instead of little-endian

I didn't know that the PowerBook G4 also used KeyLargo. Does the Screamer
chip in it support little-endian samples? Does anyone know?
