That's pretty common.  At least it used to be way back when.

It's my understanding that there are two ways of playing a CD in a computer:

1. analog extraction
2. digital extraction

Analog extraction is where the the cd is read, the signal goes through a
cable between the cd player and sound card, which gets pumped through your
speakers.  Point being, a physical connection between the cd drive and sound
card is required.

Digital extraction is where the cd is read, and the signal gets pumped
through the ATA port to your speakers.  This is more efficient from the
CPU's standpoint.

At least that's my understanding.

My permissions are:

   brw-rw----  1 root cdrom 22, 0 2006-01-18 04:28 /dev/hdc

Rather than play with permissions, you may want to play with groups:

1. chmod 660 /dev/hdc
2. chgrp cdrom /dev/hdc
3. add the usernames you want to give cd access to /etc/groups

Not crucial.  Just an alternative.
