AFAIK, artsd should *not* be running, but rather pulseaudio instead of it. And 
it should not get started automatically by anything, either.

FWIW, I am having trouble to reproduce anything that was discussed in this 
thread, on this F12/KDE/64bit (fully updated). Sound works here without 
problems, pulseaudio is active, and systemsettings -> multimedia -> output 
device preference has only one stanza, "internal audio analog stereo" for all 
device categories. As for backend, xine is prefered over gstreamer. And it 
just works since F12 came out. Although the possible output device stanzas 
have been changing from time to time, automatically, as updates came by... I 
remember seeing pulseaudio and pulseaudio server on that list simultaneously 
at some point. :-)

Maybe the problem has something to do with virtualization, or hardware type, 
or upgrading path (this F12 was clean install, not upgrade from F11).

HTH, :-)
