I have a problem trying to read cd's using audiocd:/ with kde 3.2 under Suse 9.1

With a CD in the drive using this produces the error message

An error occurred while loading audiocd:/:

The process for the audiocd protocol died unexpectedly.

Can anyone suggest the reason or had the same problem

I was previously running KDE 3.1 with Suse 9.0 and before that 8.2 and neverhad any problems.

Just perhaps to explain myself a little better I am trying to read the contents of audio cd's by typing audiocd:/ into the command line in konqueror which produces the response

This used to work perfectly with KDE 3.1 and Suse 9.0 but since upgrading has stopped functioning.

Hi.

I've got the same problem, but I get more and more closer to the solution.

You sure have an CD or DVD Burner?

If so, then you have to change permissions for your "different cdrom devices". If you have a Burner, linux emulates them as an scsi device...don't ask me why, I don't know .
You can look up your /etc/fstab and you will see, that there's not only your cdrom and your hd's. There's also a device called /dev/scd0 or /dev/sg0.

What you now have to do is to set the right permissions for these devices.
go to the /dev directory and type:

# ls -al cdrom*
# ls -al scd*
# ls -al sg* (there are a lot of sg* devices, so maybe sg0 and sg1 is better)
you will see the permissions these devices have. In the moment only root may have read and write permission for sg0 and scd0, and you have to change this!

As I have read in different newsgroups, you now should do the following:

type as root (user is in disk group) in /dev:
chown root scd0
chgrp disk scd0
chmod 666 scd0
---->makes root the owner of the device scd0 and gives read/write permissions to all users

chown root sg0
chgrp disk sg0
chmod 666 sg0
--->makes root the owner of the device, makes default group disk and gives read/write permission to all users from all groups.

root should be the owner of the device, because otherwise it's a security hole or something. It just important, that you give the read/write permission for all groups and users by using chmod 666.

If you have two cdrom drives in your PC then you surely have also to change the permissions for sg1 and sc1.

Check the permissions for cdrom*, too!

You will find a lot of hints by using google. Search for things like: "linux rip root" (w/o quotes)

I hope it's not too much information I gave you .
But I'm still having trouble to get it working because I cannot change the permission for my devices.
The link to my thread is the following:

http://www.linuxquestions.org/questi...hreadid=190996

I looked at the fstab file and have posted it here but it doesn't show the devices /dev/scd0 or /dev/sg0 you refered to. Someone in the Newbies forum suggested that the various cd's and dvd'd were mounted in strange places also although I have a dvd and cd rewriter it shows an entry for a cdrom and a cdrecorder. Not sure if this is a problem

fstab is as follows

dev/hde4 / reiserfs defaults 1 1
/dev/hde1 /windows/C ntfs ro,users,gid=users,umask=0002,nls=iso8859-1 0 0
/dev/hde5 /windows/D ntfs ro,users,gid=users,umask=0002,nls=iso8859-1 0 0
/dev/hde6 /windows/E vfat users,gid=users,umask=0002,iocharset=iso8859-1,codepage=437 0 0
/dev/hde3 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbdevfs /proc/bus/usb usbdevfs noauto 0 0
/dev/cdrecorder /media/cdrecorder subfs fs=cdfss,ro,procuid,nosuid,nodev,exec 0 0
/dev/cdrom /media/cdrom subfs fs=cdfss,ro,procuid,nosuid,nodev,exec 0 0
/dev/dvd /media/dvd subfs fs=cdfss,ro,procuid,nosuid,nodev,exec 0 0
/dev/fd0 /media/floppy subfs fs=floppyfss,procuid,nodev,nosuid,sync 0 0

I think you should check the permissions of:
dev/cdrecorder
dev/cdrom
dev/dvd
check also dev/sg0 because it's needed, too.

then change the permissions of theses device by using chmod 666 dev/device

The problem seemed to resolve itself I am not sure quite how.

I used KAudioCreater to rip tracks from some CD's and this seemed to sort out the problem with AudioCD as well.

The best suggestion I had was that it loaded or updated some librarys that got the audiocd working as well.

Thanks for your help though
