IOS 微信浏览器 端音乐播放问题

背景音乐自动播放
<audio src="123.mp3" preload="" autoplay="autoplay" loop="" class="audio" id="music-audio"></audio>


function audioAutoPlay(id){

        var audio = document.getElementById(id),

            play = function(){

                audio.play();

                document.removeEventListener("touchstart",play, false);

            };

        audio.play();

        document.addEventListener("WeixinJSBridgeReady", function () {
            play();

        }, false);

        document.addEventListener('YixinJSBridgeReady', function() {

            play();

        }, false);

        document.addEventListener("touchstart",play, false);

    }

    audioAutoPlay('music-audio');



js调用播放需要引用微信js
<audio src='123.mp3' preload=""  class="audio" id="userAudio"/></audio>
<script src="http://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>

function playAudioww() {
       wx.config({})
       wx.ready(function () {
           var audio = document.getElementById("userAudio");
           audio.play();
       })
        // audioAutoPlay('userAudio');
    }
