F13 KDE: phonon audio playback device does not work

[Andrea]

I've just installed a brand new Fedora 13 with KDE

Phonon says it reverts to default.
I've got a

Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio
Controller (rev 01)

But in pavucontrol I can only see Internal audio.

Any idea?
