It appears that udev is not detecting your CD-ROM drive and setting up
the appropriate cdrom -> hdc link in /dev.

Try creating a file /etc/udev/rules.d/10-custom.rules containing the
following line:

BUS="ide", KERNEL="hdc", NAME="%k", SYMLINK="cdrom"

This should cause the correct symlink to be created, which in turn
should result in the hdc device having its ownership changed from root
to whoever is logged in at the console, enabling whoever that is to
access the device. Because the device is owned by that user, there is
then no need to alter the permissions.

More likely the CD-ROM audio input on your sound card is muted or has
the volume turned right down. Try un-muting everything on your mixer and
changing the volume on all the inputs.
