Amarok 3 doesn't play music anymore

[tuomas at norsumanageri.org]

Hi Jan,
seems like your system doesn't have any Phonon backend installed (any 
more). I believe you'll need to install the package 
"phonon4qt5-backend-vlc".
(Amarok is one of the few applications using Phonon for audio playback, 
so it is not unexpected that you are not experiencing issues with other 
software's audio)

Best regards
Tuomas
