Presently you do not _need_ to write a plugin to play media, it is adviseable, 
and will be a necessity in the future.  You can copy the one from the default 
path src/plugins/audiohardware. I'll make sure a version makes it into 
devices/example.

That's a problem, which device profile are you using?

Well that's interesting, if you don't mind, what are the results 
of 'pkg-config gstreamer-0.10 --libs'?
