/dev/cdrom question: resolved (partially)

[C Toews]

Many thanks to all who responded.  Jonathan, I followed your advise, cranked 
up xmms, and using digital playback got bona fide sound.  I was very 
happy--thanks again.  I'm still investigating why the other players don't 
work, or (perhaps equivalently) what goes wrong in analog mode--I'll post my 
finding if I discover a solution.

Best regards,
Carl
