Replay issue in IE8

[AhnSeongHyun]

In above IE9, and Chrome, follow the code below to play the sound source repeatedly
console.log is below:

requestNewOrder
play
(play sound during seconds)
pause 
ended

But, The sound source is played once, then stopped in IE8.
console.log is below:

requestNewOrder
play
(no play sound)
pause 
ended

    var audio_js =null;
    $(document).ready(function (e) {
        initAudio();
        requestNewOrder();
    });

    function playAlarm(){
        if(audio_js) {
            audio_js.play();
        }
    }

    function requestNewOrder(){
    	console.log(requestNewOrder);
        var url = "/new_order";
        var success_func = function(result){
            if(result.data.new_order_count> 0) {
                playAlarm();
            }
            else{
                setTimeout(requestNewOrder, 2000);
            }
        };

        var error_func = function(){
            setTimeout(requestNewOrder, 2000);
        };
        commons.request(url, params, success_func, error_func, null); //Custom Ajax Library
    }

    function initAudio () {
        audio_js = new Audio5js({
            ready: audioReady,
            play:function(){
                this.play();
            }
        });
    }

    var audioReady = function () {
        this.load('/static/audio/order.mp3');
       
        this.on('play', function () {
            console.log('play');
        }, this);
        this.on('pause', function () {
            console.log('pause');
        }, this);
        this.on('ended', function () {
            console.log('ended');
            requestNewOrder();
        }, this);
    };

Try seeking the audio to position 0.
I suspect this is due to some discrepancy in the Flash player (IE8) vs. the HTML5 player (IE9+).
