Opentok和CallKit的問題

Question

我正在嘗試使用Opentok和CallKit進行音頻和視頻通話，我已經按照OpenTok提供的這個演示了https://github.com/opentok/CallKit/tree/master/CallKitDemo

我面臨的問題是，當我向另一個人進行音頻通話時，它會啟動揚聲器而不是內置接收器。 我嘗試了他們的演示，它也有同樣的問題。

然后我嘗試了Apple提供的https://developer.apple.com/library/content/samplecode/Speakerbox/Introduction/Intro.html#//apple_ref/doc/uid/TP40017290 ，但是在實現AudioController ，新的呼叫以內置揚聲器開始，並自動切換到揚聲器，無法進行輸出更改。

你是如何發布你的流的？

 let settings = OTPublisherSettings()
 settings.name = "\(userID)"
 guard let publisher = OTPublisher(delegate: self, settings: settings) 
  else {
        return
    }
    yourStream = publisher
    yourStream?.publishAudio = false
    yourStream?.publishVideo = true
    var error: OTError?
    session?.publish(publisher, error: &error)
    guard error == nil else {
        print(error!)
        return
    }

    guard let publisherView = publisher.view else {
        return
    }
   participantVideoView.addSubview(publisherView)

我需要通過設置AVAudioSession來實現自定義音頻驅動程序

         var audioOptions: UInt {
            if isSpeaker {
                return AVAudioSessionCategoryOptions.defaultToSpeaker.rawValue |
                    AVAudioSessionCategoryOptions.mixWithOthers.rawValue |
                    AVAudioSessionCategoryOptions.allowBluetooth.rawValue |
                    AVAudioSessionCategoryOptions.allowAirPlay.rawValue

            } else {
                return AVAudioSessionCategoryOptions.mixWithOthers.rawValue |
                    AVAudioSessionCategoryOptions.allowBluetooth.rawValue |
                    AVAudioSessionCategoryOptions.allowAirPlay.rawValue |
                    AVAudioSessionCategoryOptions.duckOthers.rawValue
            }
        }
        if isSpeaker {
            try session.setCategory(AVAudioSessionCategoryPlayAndRecord, mode: AVAudioSessionModeVoiceChat, options: AVAudioSessionCategoryOptions(rawValue: audioOptions))
        } else {
            try session.setCategory(AVAudioSessionCategoryPlayAndRecord, mode: AVAudioSessionModeVoiceChat, options: AVAudioSessionCategoryOptions(rawValue: audioOptions))
        }
