[]有没有SoundChannel的示例？

SoundManager.playSound(_url, _loop, new Handler(this, _fn));

var channel:SoundChannel = new SoundChannel();
SoundManager.addChannel(channel);

_btn.on(Event.CLICK, this, soundClick);
function soundClick(evt:Event){
alert("channel.isStoped:"+channel.isStoped);
if (channel.isStoped){
channel.play();
}else{
channel.stop();
}
}

channel.isStoped输出是：undefined
