All Phonon based apps (I've tried Kadu, Phonik (aur), and my little app) fail to initialize Phonon backend: WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::AudioOutput ( no objectName ). I have backends installed: [kaz@Dmitrij ~]$ pacman -Qs phonon local/phonon 1:4.6.0-1 local/phonon-gstreamer 4.5.1-1 local/phonon-vlc 0.4.1-1 I've tried with only one backend installed (tried both...), but it still doesn't work. I'm using testing repo if that matters. Is it something with my configuration or is it a bug in Arch Linux?
