on the line where you instantiate your sound change:
var whatever:Sound=new Sound();
var whatever:Sound=new Sound(this);
Man, you`re fast!
And all over the place, it seems... For years now, whenever I look for solutions to my Flash problems, at least some of the answers are from you!
Just wanted to say thanks and that I eventually found this same answer from you on another post here on the forums, and it solved my problem.
So, thanks Kglad!
(and, believe it or not, i've also searched for solutions to problems using google and, not infrequently, found an answer given by me so long ago, i'd forgotten the solution.)
