[Qt-interest] Phonon backend plugin WARNING

[Keshava Krishna]

hello everyone,

I am using qt 4.5.0 and i tried to run musicplayer example of phonon, the
application is not  running as expected,
it gave following warnings..

keshava at keshava-desktop:/usr/lib/qt4/examples/phonon/musicplayer$
./musicplayer WARNING: bool Phonon::FactoryPrivate::createBackend() phonon
backend plugin could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin

WARNING: Phonon::createPath: Cannot connect  Phonon::MediaObject ( no
objectName ) to  Phonon::AudioOutput ( no objectName ).
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded

i could understand that it is not able to find a backend plugin,
can anyone please suggest me how to set the backend pluggins??
