mySound = new Sound();
mySound.attachSound("mySound1");
mySound.start();
onEnterFrame = function () { pausedTime = math.floor(mySound.position / 1000); };
control_sound.onPress = function() {
    if (this._currentFrame == 1) {
        this.gotoAndStop(2);
        _root.mySound.stop();
    } else {
        this.gotoAndStop(1);
        _root.mySound.start(pausedTime);
    }
};

这是一段声音控制AS，一开始播放是ON 要怎么改能使默认的是OFF
