actionscript-3 - Actionscript 3：Event.SOUND_COMPLETE 不会触发

Question

好的，所以我正在为我正在制作的网站开发我的简单 actionscript-3 声音播放器......在这样做的同时，我发现 SOUND_COMPLETE 事件由于某种原因没有触发。因此，如果有人似乎注意到我的代码中的问题，请回复！

package {
    import flash.events.*;
    import flash.media.*;
    import flash.external.*;
    import flash.net.*;
    import flash.utils.*;

    public class player{

        private var soundChannel:SoundChannel;
        private var sound:Sound;
        private var lastPosition:Number = 0;

        public function player():void{
            ExternalInterface.addCallback("load", this.load);
            ExternalInterface.addCallback("play", this.play);
            ExternalInterface.addCallback("stop", this.stop);
            ExternalInterface.addCallback("reset", this.reset);
        }
        /*
        javascript from inside actionscript:

            ExternalInterface.call("console.log","ipsum");
        */
        private function load(url:String):void{
            var audio:URLRequest = new URLRequest(url);
            try {
                this.soundChannel.stop();
            } catch(e:Error) {
            };
            this.sound = new Sound();
            this.sound.load(audio);
            this.lastPosition = 0;
        }
        private function play():void{
            this.soundChannel = this.sound.play(this.lastPosition);
            this.soundChannel.addEventListener(Event.SOUND_COMPLETE,finished);
            ExternalInterface.call("console.log","started playing");
        }
        private function finished():void{
            this.lastPosition=0;
            this.soundChannel=this.sound.play()
            ExternalInterface.call("console.log","finished playing");
        }
        private function reset():void{
            this.lastPosition = 0;
            this.soundChannel.stop();
        }
        private function stop():void{
            try {
                this.lastPosition = this.soundChannel.position;
                this.soundChannel.stop();
            } catch(e:Error) {
            };
        }

    }
}//package

我认为问题在于finished()不接受事件，它应该是：

    private function finished(e:Event):void{
        this.lastPosition=0;
        this.soundChannel=this.sound.play()
        ExternalInterface.call("console.log","finished playing");
    }
