我使用了从github下载的alexa skill-sample-nodejs-audio-player。该技能中有4个音频流。所有音频流都在回声点设备中逐一播放。然后我在混响中进行测试，发现它只播放了两个音频流，然后卡住了。
从所附的Cloudwtach中，我发现第二个音频流中的事件“ AudioPlayer.PlaybackNearlyFinished”无法正常工作，它没有响应以下音频流url，而是发出“类型”： System.ExceptionEncountered”。
可能是混响错误吗？因为它在回声点中工作正常。我尝试了音频播放器的几种不同的网络技巧，结果是相同的，它被卡在第二个音频流中，并拒绝继续播放。
有人有同样的问题并且知道如何解决吗？
