   I have nothing for this.  I am guessing that mplayer reads audio data   
   from CDROM and writes it to ALSA.

   It tells me cdp is not using ALSA.  It's telling the CDROM to play a   
   track on its line out.  I'd double-check the mixer to make sure   
   nothing is muted.  I'd also want to verify that the line out is   
   actually connected to the audio hardware.  It brings to mind a   
   standard tech support question: When was the last time this worked   
   on this hardware?  Which version of Slackware was it then?   
      
   Best regards,
