I may be misunderstanding the documentation here, but the constructor
described in:

http://doc.trolltech.com/4.6.2/phonon-mediasource.html

says:

"MediaSource::MediaSource ( const QString & fileName )

Creates a MediaSource object for the file specified by fileName. You
can also use this constructor with Qt resources"

Although I've just noticed the examples in:

http://doc.trolltech.com/4.6.2/phonon-mediaobject.html

which just pass a resource style filename to 'setCurrentSource'.

That's fine, TBH, unless the user changed sounds a lot I'm not tooo
worried about a single file object hanging around until exit, but to
be sure I'll change it to a class variable or similar.

Thanks for the feedback. :)
