I suppose you are using the default KDE 4.2.2, right? Then you have a
KDE3 version of Kaffeine and need the correct libraries. I suggest
using Dragon Player or VLC instead.

Sound with Flash is another problem, but this is often due to a
conflict and has not been definitely solved for now. The culprit is
definitely Flash, and it causes problems, especially with the 64bit
architecture. Normally the package flashplugin-installer in the
multiverse repository should provide you with the correct flash
version, installing from Adobe is not recommended.

FWIW, it seems that Opera can handle Flash better than Firefox. I
currently use Firefox-3.5 and Konqueror in KDE 4.3 in Jaunty and
Konqueror seems to be able to handle Flash a bit better. But still,
every now and then I have to restart the browser as the sound goes
wild.

Pulseaudio is definitely not part of Kubuntu Jaunty, the default
should be phonon with the xine backend. Installing  openoffice.org
unfortunately drags in pulseaudio and this leads to more than strange
audio results. The current pulseaudio configuration is made for Gnome
only and it needs quite some tweaking to make it work in KDE.

For now, the easiest and probably best solution is to remove
pulseaudio (there will be a remaining library called libpulse0 one can
not remove without compromising KDE4) as the KDE applications do not
need it, set the phonon backend to xine and remove gstreamer if it has
been installed. The codecs can be found in kubuntu-restricted-extras.

VLC should work without problem, I guess pulseaudio is again to blame
and removing it should solve that. Make sure you have all three needed
packages installed: vlc, libvlc2 and libvlccore0


Hope this helps.


Regards, Myriam.
