Triggering a Sound object once the SWf is loaded into a container SWF

Greetings Flash Heads,

I have a created a sound object like so:

//Creating the Sound Object
sliderSound = new Sound();
sliderSound.attachSound(“slideInSound”);
sliderSound.setVolume(20);

I then trigger the sound from a number of buttons like so:

someButton_mc.onRelease = function() {
sliderSound.start(0,1);
}

It works great when viewed. the problem is that when I load this SWF file into an container SWF file (using loadMovie) the sound will not play.

Any suggestions?

I’m all set.

sliderSound = new Sound(this);
