OpenSUSE :: K3B Audio CD Burn Fails

I recently installed OpenSuse 11.1 (i586) on a new laptop (HP 6710b) all has been going well, until I tried to burn audio CDs with K3B using .wav files in a directory in the format 01.wav 02.wav 03.wav etc. To burn the audio CDs I have been running K3B as root to avoid any potential permission issues. I now have a stack of cd 'coasters' with only one lucky success using the command line, which when the exact command was repeated failed again. I have successfully burnt 2 data DVDs using K3B, one as root the second as user, both without problem - so maybe it is not a permissions problem?

I am using K3b 1.0.5 in KDE 4.1.3. (it runs under KDE3) I have not been able to run k3bsetup � it is not part of the installation. However permissions appear correctly set-up � I also added the appropriate users to the group �disk�.

/dev/cdrom lrw-rw----root disk (just points to /dev/sr0)
/dev/sr0 -rw-rw---- root disk
/usr/bin/cdrecord lrwxr-xr-x root root (just points to /usr/bin/wodim)
/usr/bin/wodim-rwxr-xr-xroot root

K3b uses the executables in /usr/bin/x11/ which are just the same. I have not put suid on anything. I tried running cdrecord as a user, however the burn failed.I checked the .wav files and they play fine in kaffeine. I am using the same brand of blank CDs as the DVDs.I have not had the occasion to try a data CD � I've run out of blank disks for the moment.

K3b detects my DVD/CD burner as:

The system device is /dev/sr0
interfaceGeneric SCSI
Vendor HL-DT-ST
DescriptionDVDRAM GSA-T40L
FirmwareKC07

I tried burning audio CDs in both TAO and DAO mode, neither with success.

Here is an example shortened K3b output:

scsidev: '/dev/sr0'
devname: '/dev/sr0'
scsibus: -2 target: -2 lun: -2
