kscd and k3b ?.

Hi. On my SuSE 9.1, I have some problems. If I put an audio CD in the cdrom drive, kscd doesn't start up as it normally has done. Nor will the system play the music. If I want to burn a CD with K3B, I cannot do that as user, but ok if being root. What can be wrong here ?. Where is the logfiles for the problems to be found ?. Erik Jakobsen.
