Stop sounds with javascript?

hi there,

i’m not shure if I’m on the right forum, but here comes my question:

I’ve made a flashnavigation with sounds on the rollOver status of each button.
But some people may find this annoying, so I want a function to turn them off.
Problem is that I don’t have enough space in my flash movie to make another button with the following code:


volume = new Sound();

button.onRelease = function(){    
      volume.setVolume(0);
};

So I want to do this with JavaScript. Is there someone who knows how?
If so, I would be forever greatfull!
