Flash Sound problem

I really hope someone can help me. I’m trying to play sound in my site. The code that I’m using is:

loadMovie(“girl_intro.swf”,mv_main);

And while it does load just fine, after it plays for a bit, it sounds like it’s playing over itself, like it’s plays twice at the same time. I’ve tested my sound swf file and it’s not that file as it’s fine. I think the problem is when it loads. does anyone know how to fix this? :frowning:
