[kde-linux] No sound with phonon and kde4.1

[SeaJey]

kde 4.1 mini-howto (kubuntu 8.04):

Execute in terminal:

mv /usr/lib/oss/lib/libsalsa.so.2.0.0 /usr/lib/oss/lib/libsalsa.so.2.0.0.bak
ldconfig

Install latest gstreamer and plugins from ubuntu ppa:
deb http://ppa.launchpad.net/gstreamer-team/ubuntu hardy main
Also uninstall gstreamer-alsa (for sure)

Move gstreamer to the first place in phonon-backends list in "Sound" section 
of "System Settings".

And sound is magically working now! Volume control at application level too.
Tested with juk-kde4 and dragon player.

Some issues still remain:
Sound configs can be changed only via ossxmix or ossmix.
qtconfig says that there is no gstreamer phonon-backend at all - but it could 
be only (k)ubuntu trouble.
