Comment 12 for bug 131475

Attach is a patch that remove the lock feature from sound-juicer.
At this state of Gutsy, it's might be too intrusive to create a patch that make sure that the drive is unlocked whatever sound-juicer is exited normally or crash. For now, it's better to make sure that the drive is not locked at all by sound-juicer.
Anyway, this is not something that useful. It's quite uncommon to burn a CD while extracting music from it.
And since the default audio CD burner application Serpentine don't respect this lock state, this is not useful at all.
