Start/Stop Audio using JavaScript

Hi.

I need some help getting an auto icon button on my project to both play and stop/pause a sound. I'm currently using the following, but don't know how to tell it to resume the sound.

this.music.addEventListener("click", fl_MouseClickHandler_6.bind(this));

function fl_MouseClickHandler_6()

{

    createjs.Sound.stop(); 

}

Thank you.
