fail jsapi has no permission应该是类目没有权限，sapi permission required playing audio but current not playing audio in background state这个部分呢？我们基本上ios都会报这个错，部分安卓机型也会。是微信不准后台播放吗？

我们很简单的需求，小程序进去某个页面有十几个音频，点第一个可以播放，然后希望第一个播放完了自动播放下一个音频，

在播放下一个的时候就报这个错了。

title，epname也设置了值。

app.json里已添加：

“requiredBackgroundModes”: [

“audio”

]
