Pls help: sound problem!

1

so:
soundHCS = new Sound(soundMc);
soundHCS.attachSound(“soundHCS01”);

2 buttons:
first frame button:
on (press) {
_root.soundHCS.start(0,999);
gotoAndStop(2);

}

second frame,button:
on (press) {
gotoAndStop(1);
_root.soundHCS.stop();

}

works perfect, but I want the page to be loaded with sound on(with no need to push button 1), and then me to push button 2.

any idea?
many tkx!
