Start sound immediately...?

http://www.kirupa.com/developer/mx/volume_slider.htm

i am following these tuts but evrything is working fine but what i want is that my music should start playing immediately as it is loaded rather then waiting to click button to play…

so far i tried is:

[color=navy]onClipEvent (load) {
mySound = new Sound();
mySound.loadSound("_jUsT-Rudy_Ves-8003_hifi.mp3", false);
[/color] [color=darkorange]mySound.onLoad = playSound();
function playSound(success) {
if (success) {
mySound.start();
}
[/color] [color=navy]}
}
onClipEvent (enterFrame) {
downloaded = mySound.getBytesLoaded();
total = mySound.getBytesTotal();
if (downloaded != total) {
_root.dl = “downloading song…”;
} else {
complete = 1;
_root.dl = “playing”;
}
mySound.setVolume(_root.volume*2);
}
[/color]
