Sound loader/controller plugin

[Ricardo]

In my Flash virtual tours I'm using a sound controller that loads (using loadMovienum()) different musics (i.e. music1.swf). You can see an example here: www.tourvirtualbrasil.com.br/rio_othon
I just tried to add this controller as a plugin. I can see the controller but the sound does not work.
Here is my code:
First Frame: loadMovieNum("music1.swf",1);
In each button, some like that:
on(release) {
loadMovieNum("music4.swf",1);
_root.soundstatus="on";
_parent.equalizer.gotoAndStop(1);
_parent.gotoAndStop(1);
}

Any tip?

Thanks in advance.
