Try this on your computer: ls -l /dev | grep cdrom and ls -l /dev | grep audio You'll see that root is the owner of these devices and always has all access rights. Every user who is part of the group cdrom resp. audio has some rights as well, because the devices have that group ownership. Anyone not root or not in these groups has no rights to these devices in the default debian setup. Root (or in general, the owner of the device/file) can change this and give all others additional rights, but that is not good policy. You'll want to add the users that must be able to read the raw cdrom device (as opposed to a mounted filesystem on the cdrom) to the cdrom group. The same with group audio. This is done with the adduser command. adduser <username> <groupname> will add <username> to <groupname> (don't actually type the <'s and >'s, those are special characters and may confuse the shell and you.) The permissions thing with owners and groups is really basic to unix, you should read the manpages for adduser, chown and chmod before proceeding. man adduser man chown man chmod and man man man is your friend.
