Ubuntu currently uses:

  ALSA (low-level) <- OSS (interface) <- esd (multiple-sources) <- Programs

so currently you have to set programs to use 'esd';  or disable/kill 'esd' 
to get programs that want to talk OSS to work (only one application at a
time though).

The long-term plan is to have a setup that accepts OSS, ESD, ALSA, gstreamer
APIs and mixes the whole lot with 'dmix' onto of ALSA.

 (a) Did it work before?
 (b) Do you have a physical audio cable?  If so, try enable CD audio in the
 (c) Otherwise, player needs to 'rip' it from the drive and feed it back as
     PCM wave data (through ESD).
