JQuery在Mac中播放声音文件不起作用

 var audio = document.getElementById("myAudio");

 $("#playButton").click(function() {

   audio.play();

 });

 $("#pauseButton").click(function() {

   audio.pause();

 });

 $("#stopButton").click(function() {

   audio.pause();

   audio.currentTime = 0;

 });

 var audioContext = new (window.AudioContext || window.webkitAudioContext)();

 var audioBufferSourceNode = null;

 function loadSound(url) {

   var request = new XMLHttpRequest();

   request.open('GET', url, true);

   request.responseType = 'arraybuffer';

   request.onload = function() {

     audioContext.decodeAudioData(request.response, function(buffer) {

       audioBufferSourceNode = audioContext.createBufferSource();

       audioBufferSourceNode.buffer = buffer;

       audioBufferSourceNode.connect(audioContext.destination);

     });

   };

   request.send();

 }

 $("#playButton").click(function() {

   if (audioBufferSourceNode) {

     audioBufferSourceNode.start();

   } else {

     loadSound("path/to/soundfile.mp3");

   }

 });

 $("#pauseButton").click(function() {

   if (audioBufferSourceNode) {

     audioBufferSourceNode.stop();

   }

 });

 $("#stopButton").click(function() {

   if (audioBufferSourceNode) {

     audioBufferSourceNode.stop();

     audioBufferSourceNode = null;

   }

 });
