Can you try 3 things to help clarify the problem - other people who have reported a similar problem have not been forthcoming with additional info that would help pin point the problem.

Can you try the following and let me know what happens in each case:

1. use mpg123 to play an audio file (no gui that may hide error messages).
   Does it appear to be playing the file?  eg doesn't complain about not 
   being able to open the device.

2. Configure your mp3 player to play at a rate lower than 44.1kHz, eg try
	mpg123 -2 foo.mp3

3. Configure your mp3 player to use /dev/audio rather than /dev/dsp?  And try playing the same file.
	mpg123 -a /dev/audio foo.mp3

Thanks
- Orion
