Please disable Pulseaudio in your sound settings, Phonon doesn't work well with Pulseaudio in your version.
If you are running Kubuntu without Gnome, I strongly suggest you remove Pulseaudio, since KDE doesn't need it anyway. This should be solved in the new KDE SC 4.4
Comment 2 Sergio Del Franco 2010-02-12 05:02:09 UTC
In every case, PulseAudio was the second preferred device. Maybe preferred device was locked (Flash?) and Amarok used the second one?
Comment 3 Sergio Del Franco 2010-02-12 05:05:53 UTC
# aptitude why pulseaudio
i   libpulse0 Sugiere pulseaudio
# aptitude why libpulse0
i   kdebase-runtime Depende libpulse0 (>= 0.9.19)

Should I report a bug in Ubuntu's kdebase-runtime package?
Comment 4 Sergio Del Franco 2010-02-12 05:07:59 UTC
When it says: "Sugiere"
you should read: "Suggest"

When it says: "Depende"
you should read: "Depends on"

Not at all, since KDE is not using Pulseaudio at all in Kubuntu. You need to select your soundcard directly and use the xine backend.
