Ios Sinch视频通话声音来自前扬声器

我已经在ios swift项目中实施了sinch视频通话，我遵循了sinch实施文件中给出的所有流程。我成功地实现了，但我的视频声音来自前置扬声器。我怎样才能解决这个问题？？下面是我的代码：

var client: SINClient?
var sinCall : SINCall?

配置sinch

//MARK: Configuring Sinch Delegate
func configuringSinch(){
    //Configuring Client Key
    client = Sinch.client(withApplicationKey: Constants.SINCH_APP_KEY, applicationSecret: Constants.SINCH_PRIVATE_KEY, environmentHost: Constants.SANDBOX_ENVIRONMENT, userId: Utility().getUserId())

    client?.call().delegate = self
    client?.setSupportCalling(true)
    client?.enableManagedPushNotifications()
    client?.start()
    client?.startListeningOnActiveConnection()

    let vcCont = client?.videoController()
    self.vwLocalView.addSubview((vcCont?.localView())!)

    self.sinCall?.delegate = self

}

//MARK: Sinch Video Call Delegate
func clientDidStart(_ client: SINClient!) {
    print("Client Did Start")
}

func clientDidFail(_ client: SINClient!, error: Error!) {
    print("Client failed : \(error)")
    player?.stop()
}
func clientDidStop(_ client: SINClient!) {
    print("Client Did Stop")
    player?.stop()
}

    //MARK: Video Call Did Recieve
func client(_ client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {
    print("Did Recieve Incoming Call")

    playRingtoneSound() // Playing Audio
    call.delegate = self;
    self.sinCall = call
}

 //MARK: Call Did Add Video Track
func callDidAddVideoTrack(_ call: SINCall!) {
    let videoCont = client?.videoController()
    vwRemoteView.addSubview((videoCont?.remoteView())!)
}

func callDidEnd(_ call: SINCall!) {
    sinCall?.hangup()

}

这就是您如何管理SINAudioController来管理音频输出的方法

func audioController() -> SINAudioController {
        return (client?.audioController())!
    }

//MARK: Video Call Did Recieve
func client(_ client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {
    audioController().enableSpeaker()

    playRingtoneSound() // Playing Audio
    call.delegate = self;
    self.sinCall = call
}

// In SINCallDelegate
func callDidEstablish(_ call: SINCall!) {

    //to disableSpeaker
    audioController().disableSpeaker()
}

尝试手动管理音频输出会话

// MARK: AudioOutput Session

// to enable front speaker manually
func setSessionPlayerOn()
{
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)
    } catch _ {
    }
    do {
        try AVAudioSession.sharedInstance().setActive(true)
    } catch _ {
    }
    do {
        try AVAudioSession.sharedInstance().overrideOutputAudioPort(AVAudioSessionPortOverride.none)
    } catch _ {
    }
}

// to enable speaker manually
func setSessionPlayerSpeaker()
{
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)
    } catch _ {
    }
    do {
        try AVAudioSession.sharedInstance().setActive(true)
    } catch _ {
    }
    do {
        try AVAudioSession.sharedInstance().overrideOutputAudioPort(AVAudioSessionPortOverride.speaker)
    } catch _ {
    }
}

// to turnoff AudioOutput Session manually
func setSessionPlayerOff()
{
    do {
        try AVAudioSession.sharedInstance().setActive(false)
    } catch _ {
    }
}

使用此功能

 func callDidEstablish(_ call: SINCall!) {

    let audio = APPDELEGATE.client?.audioController()
    audio?.disableSpeaker()

   // self.startCallDurationTimerWithSelector()
    appDelegate.client?.audioController().stopPlayingSoundFile()

}

这是我的工作。

这与我在视频通话时接收的传入声音无关。好的，但当您在“来自前扬声器的视频声音”中写入时，它将从扬声器输出。您可以在控制器audioController（）中的任何位置使用它。enableSpeaker（）。让我知道这是否有用我已将答案编辑为audioController（）。enableSpeake不适用于您。您可以手动管理音频输出会话以实现此目的。您的问题是否仍然存在？修复了@Govind的问题
