Sinch视频通话声音来自前扬声器

Question

我已经在iOS Swift项目中实现了SINCH视频通话，我遵循了SINCH实施文档中给出的所有过程https://www.sinch.com/docs/docs/video/ios/#calling。我已经成功实施了，但是我会从前扬声器中发出视频声音。我怎么解决这个问题？？在我的代码下方：

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()
}

Answer 1

这就是您可以管理 sinaudiocontroller 来管理音频输出的方式。

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()
}

尝试以此操作来管理AudioOutput会话手动

// 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 _ {
    }
}

Answer 2

使用此功能

 func callDidEstablish(_ call: SINCall!) {
    let audio = APPDELEGATE.client?.audioController()
    audio?.disableSpeaker()
   // self.startCallDurationTimerWithSelector()
    appDelegate.client?.audioController().stopPlayingSoundFile()
}

这对我来说是有效的。
