PulseAudio and Jack Audio Connection Kit not installed, but Multimedia section of System configuration show it

[RussianNeuroMancer]

I use Kubuntu Lucid since Alpha 2.
PulseAudio and Jack Audio Connection Kit not installed, but I see it in Multiomedia section of System configuration.
When I try to playback test sound using it I get expected error - it's not work.
So, why I see PulseAudio and Jack in Multimedia applet?

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!

I test this bug with release version of Kubuntu Lucid. Now PulseAudio not installed but default, but systemconfig detect install Jack shared libraries package (libjack) and show not working Jack audio output.
libxine and libasound depend by libjack. But why? It's really necessary?
