No audio output when playing CDs

[John Halton <johnhalton@gmail.com>]

Since the recent ALSA upgrade (that seems to have caused a number of 
problems for other people) I'm now unable to play audio CDs on a number 
of applications (gnome-cd and XMMS, for example).

I can play them fine on Amarok, but would prefer to get the other apps 
working to avoid having to start up Amarok just to play a CD.

Any suggestions?
