 I don't understand you. I mean the 'mplayer' use the same devices like 
'xmms' (/dev/dsp or/and /dev/audio)
and 'xmms' have NOT problem. Also 'mplayer' have not problem like root. 
The problem is  'mplayer' like user.
 But I don't understand why, because 'xmms' like user work OK.
  I guest that there are some where some problems of permissions, but 
where ???
