How to play audio CDs with linux 2303

THANKS! I've done as you suggested and now CD audio works perfectly for the non-root user. So, everything is now set all right.

Actually, by running 'gpbuttwd -a youruser cdrom' user was added to group cdrom inetc-gpbuttwd andetc-group and this achieved the objective. As Aragorn pointed out later, I do have udev on my system, which would reset permissions at bootup. The system now works fine, so I'm not going to experiment further with permissions...

I want to thank everyone who participated in this thread for all the precious advice I got here. These newsgroups are truly a goldmine of knowledge, and you guys are what makes this a reality.

So, to resume the steps which solved the sound problems in my system:

1) Initially I would get an error message when attempting to run KsCD to play an audio CD as the non-root user. By running KsCD as root, which took care of the error message, it was established that there was an access permission problem. But still there was no sound.

2) Some suggested that a missing cable between cdrom drive and sound card could be the problem. Others said it could not be an issue here. I checked and there was no cable. I added a cable connecting cdrom drive and cd audio connector on the motherboard. Still no sound for su. But the music could be played by plugging a set of earphones directly into the cdrom drive.

3) Sound for root was made possible by unmuting and turning up the cd volume control in alsamixer. (Very stupid, isn't it? but I had overlooked it).

4) Finally, access permissions for non-root user. 'ls -lLdev-cdrom' produced:

brw-rw---- 1 root cdrom 22, 0 Jul 7 08:25dev-cdrom

showing that non-root user had no access todev-cdrom. Non-root user was given access permission and added to group cdrom by running:

'gpbuttwd -a username cdrom'

After logging out of XWindows then logging in again, audio CD playing now works perfectly also for the non-root user.

Again, thank you all!!!
