又一个遇到这个问题的，贴出我得错误log来，上面的爸爸们谁解决了这个问题，回复一下。

[avas]     AVAudioSession_iOS.mm:1149  Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session.

兄弟，问题解决了么？遇到同样问题了，尝试了很多方法都没效果。

但是我没单独调用线程进程，是 唤醒识别之后调用的合成，我试着注销掉speech的那段代码就可以，[[BDSSpeechSynthesizer sharedInstance] speakSentence:@"您好。" withError:&speakError] 这段，这个要怎么stop，而且我试着[[BDSSpeechSynthesizer sharedInstance] cancel];了，也没用

应该是之前的进程没结束，你的输入输出设备要在被停止或暂停之后再进行唤醒

AVAudioSession.mm:1079:-[AVAudioSession setActive:withOptions:error:]: Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session.

AVAudioSession.mm:1079:-[AVAudioSession setActive:withOptions:error:]: Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session.

具体的报错是什么
