When I insert a new CD-Audio, gxine fires up and starts playing it. As I didn't find any relevant option in gxine I suspect Xfce might be the culprit. So how do I stop Xfce from cueing gxine that a new disk has been inserted?
The volume manager launches this app. If you're using thunar-volman you can configure its settings in thunar -> edit -> preferences -> advanced -> configure (or run thunar-volman -c). If the gnome volume manager is used, run gnome-volume-properties.
PS. just reported a bug to add a desktop file to thunar-volman to launch the settings dialog (Bug #3225).
Excellent, thank you, Xerv. You're tha man!
Except if you're a woman, of course, in which case you'd be tha woman.
