Does this directory (/mnt/cdrom) exist?  Make it, put that line back in
/etc/fstab and try again.

This sounds to me like a hardware problem - i.e., you need to have an
audio cable going from your CDROM to your "sound card".  Since you
don't seem to have an actual sound card, you should check to see if
there is a slot on the motherboard to plug an audio CD cable into.  The
Crystal PNP Audio System is in fact your sound card; IIRC, that
particular model is usually built into the motherboard.  Where do your
speakers plug in?  There might be a connector near there.  Also, does
playing a CD through the speakers work in Windows?

If that's all right, then check the volume setting in linux; after
that, I'm stuck.

You should be able to look at the cd after you get the mounting bit
fixed.
