Hi,

  1. > rpm -qa|grep qt4
  2. libqt4-sql-4.4.1-25.1

I played around a little with Phonon - or at least I tried to.
I compiled the capabilities example and it runs fine. It lists all my sound devices and a long list of supported MIME types.
After that I compiled the music player example. Again it compiles and runs. But when I try to add a file, the dialog pops up, I select a file, press OK, and nothing happens I added some debugging code but found no error, just the signal stateChanged (...) connected in constructor
Qt Code: 
  1. connect(metaInformationResolver, SIGNAL(stateChanged(Phonon::State,Phonon::State)),
  2.              this, SLOT(metaStateChanged(Phonon::State, Phonon::State)));
To copy to clipboard, switch view to plain text mode 

never fires, the state of metaInformationResolver is 0 (Phonon::LoadingState).

I tried various file types, ogg, mp3, wav, ac3, always the same result.
I can play all these files with xmms or MPlayer, so no problem on this side.

Any suggestions?
