我有以下代码在Javascript中加载音频。

在Firefox中，该流立即开始播放，但是在Safari中，它需要几分钟才能开始播放，为什么？

var audioPlayer = {

track_element: [],track_state: [],context: [],audio: [],analyser: [],source: [],trigger: function (e,id,src) {



    if ( this.track_element[id] === undefined ) {

        this.context[id] = new (window.AudioContext || window.webkitAudioContext)();

        this.audio[id] = new Audio();
        this.audio[id].autoplay = true;
        this.audio[id].crossOrigin = "anonymous";
        this.audio[id].src = src;

        this.source[id] = this.context[id].createMediaElementsource(this.audio[id]);
        this.analyser[id] = this.context[id].createAnalyser();

        this.source[id].connect(this.analyser[id]);
        this.analyser[id].connect(this.context[id].destination);

        this.track_element[id] = e.target;

    }



    for ( var key in this.track_element ) {


        this.track_element[key].innerHTML = "PLAY";


        if ( this.track_state[key] ) {

            this.audio[key].pause();
            this.track_state[key] = false;

        } else if ( key == id ) {




            this.track_state[key] = true;

            this.track_element[key].innerHTML = "LOADING";

            this.audio[key].oncanplay = function(key) {
            this.audio[key].play(); 
            this.track_element[key].innerHTML = "PAUSE";
            }.bind(this,key);

        ///analyser code removed

        }

    }


}   


}

我尝试了没有分析仪的情况，这没什么区别。

我显然还要写一些文字吗？我已经解释了这个问题，我必须写多少文字？
