That IS a show-stopper! :^)

You don't want the disc mounted if you're going to play audio though.
(I somehow doubt that's happening, though -- unless the audio CD also
contains data, which some do.  Check the output of "mount" to make
sure, of course!)

IIRC, CD drives are often connected to the sound card via a little cable
within the PC itself, so that all the CPU has to do is tell the CD player
"Play", and the audio comes in as a Line to the sound card.

First off, make sure your systems' mixers are set up so that the CD audio
isn't muted, and is up loud enough.  (You'd see it in the mixer along with
a Mic input, as well as sound output and probably L/R balance and other
controls.)

Can you tell which application you're using to play CDs?  (There's probably a
"Help->About" that would tell you and app's official name and version.)
(I personally use Kscd under KDE at home.)

Can you provide the exact error message?

Not if you can rip (as you mentioned above), and if you can mount data
CDs (e.g., "mount /media/crom").  Check the contents of /etc/fstab to see
what device your system thinks the CD drive is (e.g., "/dev/hdc",
"/dev/cdrom0", etc.)

Then it might be good to make sure the CD player is looking at the same
device node...

That's probably for playing audio data that's been literally ripped off
the disc.  I don't have player handy in front of me (and have been using
Kmplayer and Kaffeine under KDE lately, since they actually have GUI controls
and stuff), but I remember for playing a DVD video with Mplayer, you
do something like:

  mplayer dvd://

Perhaps to get it to play audio from a CD you can do:

  mplayer cd://


Of course, getting a good new-fashioned GUI working with it first is probably
a good idea.  Mplayer's got more command-line switches than all other
Linux command-line tools combined![*]


Good luck!
