- 当前 Bug 的表现（可附上截图）

1、音频文件在本地或其他播放器中正常。但有的在小程序中播放不了。例如：

https://cms.hanzhigu.com/upload/audio/info/20190111/beb52979-2e0e-44c8-9d2e-dface3aa832b.mp3

2、在小程序中使用的组件是wx.getBackgroundAudioManager，上面这个音频放不了。

3、我把小程序官方提供的音频代码中SRC修改为这个，也播放不了，界面如下图，一动不动。也无错误打印信息。

使用背景播放器

- 预期表现

希望能正常播放所有的mp3文件或者支持的音频格式文件。而不是有的能播放，有的不能播放（都是MP3）

- 复现路径

- 提供一个最简复现 Demo

/*JS文件====================================================*/

const audioManager = wx.getBackgroundAudioManager();

//打开这个注释的mp3源，就可以播放

const dataUrl = 'http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guid=ffffffff82def4af4b12b3cd9337d5e7&uin=346897220&vkey=6292F51E1E384E061FF02C31F716658E5C81F5594D561F2E88B854E81CAAB7806D5E4F103E55D33C16F3FAC506D1AB172DE8600B37E43FAD&fromtag=46'

//使用下面这个播放源就无法播放。两个音频文件在浏览器中或其他本地都能正常播放
