Make sure you are a member of the "audio" group.  My mixer looks like:

crw-rw----    1 root     audio     14,   0 Mar 14  2002 /dev/mixer

Ah! Now I can eject the audio CD. How do I set the correct permissions for me to use "Volume Control"? When I try to set my volume, I get this error:


"Unable to open audio device /dev/mixer. Please check that you have permissions to open /dev/mixer and that you have sound support in your kernel."

How do I set the correct permissions for /dev/mixer? Thanks.

Still, I am unable to mount /dev/hdb or /dev/cdrom in order to play the

...and therein lies your problem. Except in very unusual cases, you don't
mount audio cd's. You play them with a program that refers directly to the
device that contains them, such as cda, xmcd, or any one of a large number
of other possible programs. Just insert the audio CD and direct the
program to /dev/hdb.
