  UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;

                           kAudioSessionProperty_OverrideAudioRoute,
                           sizeof (audioRouteOverride),

  您必须在插入耳机后覆盖音频路由 . 您的应用可以在发生这种情况时请求音频会话通知，然后再次执行覆盖 .

  这对我有用 .

  + (void)sessionAudioPort {
      UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
      AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
      UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
      AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
  }
