Bizarre Sound Object / scope problem

I set up a var : Sound = new Sound()
type sound object, and it works great... in the movie I set it up in. The way the site works, that movie is loaded in with loadmovieNum into a root movie...
and, when I test the movie like this, it refuses to play. Now I can still get sounds to play just by dumping them on the stage in the root level, but even by transfering the code that creates that sound object all into the root movie, I still can't get it to work.
Any ideas?
