Can't find audio cd

Having this problem on two different machines, both runnig 8.0. A different 7.1 installation has no problem. Xmms and Grip both do not find any files in /cdrom with an audio CD in the tray. Permissions on /cdrom, and the devices pointed to are identical between the machine where the audio CD is found, and machines where they are not. Unfortunately, I can't use the 7.1 machine for the sound editing work I need to do. Suggestions? TIA. Michael -- Michael Fischer Happiness is a config option. michael@visv.net Recompile and be happy.
