Volume Slider for Dynamically Loaded SWF

programming flash
1

I have successfully loaded “mySwf” and created buttons to stop and start the timeline. What I can’t seem to figure out is how to control the volume! I’ve looked at the tutorial here, but it wants to attach a sound – is there anyway to control the sound embedded in mySwf?

var container:MovieClip = createEmptyMovieClip("container", getNextHighestDepth());
var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.addListener(this);
mcLoader.loadClip("mySwf.swf", container);

stop_btn.onRelease = function() {
    container.stop();
};
play_btn.onRelease = function() {
    container.play();
};

Thanks in advance.
