Bingo. If you can't make the robot make sound, Player doesn't stand a  
chance. Do you have speakers connected to the internal stereo outputs?  
Do you have the sound modules loaded? Can you play a WAV file from the  
command line? Make sure that you have sound working in a normal Linux  
kind of way. Then give Player a try.
