 After starting amarok, the program gives the following warning


 {{{
 Phonon claims it cannot play mp3 files. You may want to examine the
 installation of the backend that phonon uses.
 }}}

 In reality, amarok won't play any audio file (wav, ogg, etc... )

 Starting amarok with debug options shows the following warnings


 {{{

 After searching in my system for "phonon", I couldn't find any phonon
 backend. Specially, there is no trace of phonon-qt7 or any other backend.

 Since qt4-mac is now configured with -no-phonon and -no-phonon-backend,
 one would probably need to install the backend separately.

 Can a port for phonon-qt7 be created? (Eventually, if it works it would be
 nice to also have phonon-vlc and phonon-gstreamer).

 Should the backends eventually be variants of phonon itself?
