Hi experts, When I used K3b to burn a data-projekt, everything went smooth. However, when I tried to burn some mp3-files as an audio-projekt, I got a decoding error. I pressumed the mp3 plugin could be corrupt, so I decoded the mp3 files to a wav-format (and normalize) with a batch-script. I tested those wav-files, and everything was OK. But when I tried to burn those wav-files to CD, I got the same error. Below is some debugging output the K3b application generated: ### Begin output ### System ----------------------- K3b Version: 0.11.9 KDE Version: 3.2.1-0.1 Red Hat QT Version: 3.3.1 cdrecord ----------------------- scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.25 Error trying to open /dev/scd0 exclusively ... retrying in 1 second.
