What file types are you trying to play? Make sure they are
supported by running 'audioctl -a' and looking at the channels,
rate, precision and encodings.
Check the mplayer output: if you try to play an unsupported file
type, it will default to the null audio driver and continue
without error. That might be what's happening.
There's a section in the FAQ about this -
