同时播放多个音频的问题

<audio id="audio1" src="audio1.mp3"></audio>
<audio id="audio2" src="audio2.mp3"></audio>

var audio1 = document.getElementById("audio1");
var audio2 = document.getElementById("audio2");

audio1.play();
audio2.play();

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

// 创建音频源节点
var source1 = audioContext.createBufferSource();
var source2 = audioContext.createBufferSource();

// 加载音频文件
var request1 = new XMLHttpRequest();
request1.open('GET', 'audio1.mp3', true);
request1.responseType = 'arraybuffer';
request1.onload = function() {
  audioContext.decodeAudioData(request1.response, function(buffer) {
    source1.buffer = buffer;
    source1.connect(audioContext.destination);
    source1.start(0);
  });
};
request1.send();

var request2 = new XMLHttpRequest();
request2.open('GET', 'audio2.mp3', true);
request2.responseType = 'arraybuffer';
request2.onload = function() {
  audioContext.decodeAudioData(request2.response, function(buffer) {
    source2.buffer = buffer;
    source2.connect(audioContext.destination);
    source2.start(0);
  });
};
request2.send();
