You can't mount music CDs, as the error above is telling you, they don't have
a filesystem on them (well except for those rare "multimedia" CDs). CD playing
software just accesses the device directly and tells it to play, stop, rew,
ff, etc. Then the music it played (analog) out of a special cable from the
drive that connects into the soundcard where it is mixed with your other audio
sources (like computer sounds, and other inputs). The are several mixers
available for Linux including aumix(text) and the mixers that come with Gnome
and KDE. This is the normal setup.
If you don't have a sound card
------------------------------
You can still use the CD playing software to control the drive and then plug
your headphone/speakers into the CD drive.
If you don't have the cable that connects the CD drive and the soundcard
------------------------------------------------------------------------
Some CD players have support for reading the music over the data bus (IDE or
SCSI) which is also known as "ripping"(like you'd do when encoding mp3s) and
then playing it through the soundcard. The XMMS program has support for doing
this. It's a very inefficient way of doing things since it wastes I/O
bandwidth and will slow other I/O down, but it works. Use this as an interim
approach until you can buy the $2 cable to connect your CD drive and
soundcard. I have a collection of various kinds of these cable that I can
bring to HackingSociety if needed, just ask.
HTH,
