javascript - 在IE9中设置currentTime

Question

我正在尝试从服务器流式传输音频src时设置currentTime。在其他所有浏览器上都可以正常运行，但是在IE9上，当我设置currentTime并调用play时，它会跳回到开头。

this.playAtTime = function(aTime) {
    Debug("play at time audio: " + aTime);
    Debug("this.mAudioPlayer.currentTime: " + this.mAudioPlayer.currentTime);

     this.startTime = aTime;

    if (this.mAudioPlayer.src != this.mAudioSrc) {
        this.mAudioPlayer = new Audio();
        this.mAudioPlayer.src = this.mAudioSrc;
        this.mAudioPlayer.load();
        this.mAudioPlayer.play();
        this.mAudioPlayer.addEventListener('loadedmetadata', function(){ this.currentTime = aTime / 1000.0; }, false );
    }
    else if ((isChrome() || isMobileSafari()) && aTime == 0) {
        this.mAudioPlayer.load();
        this.mAudioPlayer.currentTime = aTime / 1000.0;
        this.mAudioPlayer.play();
        Debug("Reloading audio");
    }else{

        this.mAudioPlayer.currentTime = aTime / 1000.0;
        this.mAudioPlayer.play();
    }       
};

这不是缓冲的问题，因为无论等待多长时间，它在设置时都不会成功。

尝试交换以下两行的位置:

this.mAudioPlayer.play();
this.mAudioPlayer.currentTime = aTime / 1000.0;
