Afaik, one cannot mount audio CD's in FreeBSD.
It's true, i have two devices. (Isn't it stupid that one can only use one fixed device?...
Anyway, i re-tested KsCD and Kaffeine.
Using KsCD, the audio CD is detected and starts playing but no sound. This was my original problem.
Using Kaffeine, i can hear the CD if i run Kaffeine and choose "Play audio CD".
It doesn't work if i right click the CD icon on the desktop and ask it to be run with Kaffeine.... :?
What i want (and what i think PC-BSD should do) is to have the CD playing automatically when i insert an audio CD.
Things aren't very user friendly right now are they?

This must be improved.
#UPDATE#
So i know FreebSD can't mount audio CD's. How do the media players mount them? Just for curiosity's sake?
