关于BackgroundAudioManager组件播放速度的切换，原先（一两个月前？）在ios手机上，一旦设置新的播放速度后（通过类似backgroundAudioManager.playbackRate = 1.5 这样的方式设置），音频虽然会自动重新开始播放，但至少当时播放速度也是会立马切换成新的速度值。 不过国庆前一周发现情况变了，当切换播放速度后，音频还是会重新开始播放，但播放速度不会发生变化（andriod端没问题），请问这个问题跟最近的微信版本或者基础库升级有关吗？ （特意去试了下微信读书小程序上的切换播放速度，也是有同样的问题） [图片]

BackgroundAudioManager的倍速失效了. 请查看代码片段, 并且在ios上预览. 开发者工具上是好的. 8.0.14版本前也是好的. 就是发布了8.0.14后出现的问题. BackgroundAudioManager的startTime也失效了, 暂时用seek来替代了.

用户时不时会反馈音频播放失败问题，根据搜集的错误日志来看，每天都有，而且数量不少。比较影响体验 [图片] 主要报错信息（监听wx.createInnerAudioContext()创建对象的onError方法获取）如下： 1 .Android绝大多数报下面的错 {errCode:10001,errMsg:errCode:602, err:error, not found param} {errCode:10001,errMsg:errCode:62, err:load or init native decode so fail} {errCode:10001,errMsg:errCode:67, err:decode audio fail} {errCode:10004,errMsg:errCode:55, err:unknow format} errCode:602, err:error, not found param 2 . ios绝大多数报下面的错 {errMsg:INNERERRCODE:0, ERRMSG:(null),errCode:10001} {errMsg:INNERERRCODE:-1001, ERRMSG:请求超时。,errCode:10002} {errMsg:INNERERRCODE:-1003, ERRMSG:未能找到使用指定主机名的服务器。,errCode:10002} {errMsg:INNERERRCODE:-1005, ERRMSG:网络连接已中断。,errCode:10002} {errMsg:INNERERRCODE:-1009, ERRMSG:似乎已断开与互联网的连接。,errCode:10002} {errMsg:INNERERRCODE:-1100, ERRMSG:在此服务器上找不到所请求的 URL。,errCode:10001} {errMsg:INNERERRCODE:-11800, ERRMSG:这项操作无法完成,errCode:10001} {errMsg:INNERERRCODE:-11819, ERRMSG:无法完成操作,errCode:10001} INNERERRCODE:0, ERRMSG:(null) INNERERRCODE:-11849, ERRMSG:操作停止 虽然大概率跟微信音频播放底层有关，但是想知道有没有办法，降低发生这种错误的概率？或者有什么彻底解决办法？ 每次发生这种问题，用户一般不懂技术，又是付费用户，就会对我们的产品产生不好的口碑，对我们影响挺大。但是在代码层面。程序只是调用微信提供的基础api，音频又是通用的格式，并且公司30台左右的测试设备从来没有复现到（产品已上线1年半），应该是个概率问题。 想问下各位同仁有没有遇到类似问题？有没有什么经验分享？另外求助官方大大

在iphoneX中测试，发现每次更改playbackRate后播放音频都从头开始播放，因为体验不好就在切换速度后调用seek重新回到切换前的进度，但此时好像无法正确获得播放进度？ 代码片段： https://developers.weixin.qq.com/s/6tCxq6m57znD 可以看到展示的播放进度每次切换后都是从0开始的
