Sound Object Problem

I have a Sound Object problem…obviously. My problem is strange…I have the exact same syntax and everything, but the sound plays on one FLA and doesn’t on another. ???

This is my code…this is on the ROOT time line.

var mu = new Sound();
mu.onSoundComplete = function() {
trace(“good times”);

When I generate the sound report…I get 0 bytes loaded for this sound clip. I don’t want to use “Export in first Frame” either. I’ve done this before without using “Export in First Frame” and it works, but now it doesn’t unless I do use “Export in First Frame”. Can anyone answer this?
