【中文标题】Sinch Video 通话声音来自前置扬声器【英文标题】：Sinch Video calling sound is coming from front speaker 【发布时间】：2017-12-26 11:32:49 【问题描述】：我已经在 ios swift 项目中实现了 sinch 视频通话，我遵循了 sinch 实现文档https://www.sinch.com/docs/video/ios/#calling 中给出的所有流程。而且我能够成功实施，但我的视频声音来自前置扬声器。我怎么解决这个问题？？在我的代码下面：
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()

【参考方案1】：这是您可以管理 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()
试试这个手动管理 AudioOutput Session
// 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 _

这与我在进行视频通话时收到的声音无关。 好的，但是当您编写来自前置扬声器的视频声音时，它将从扬声器输出。您可以在控制器 audioController().enableSpeaker() 中的任何位置使用它。让我知道它是否有帮助 我已将答案编辑为 audioController().enableSpeake 不适合您。您可以手动管理 AudioOutput Session 来实现这一点。 你的问题还存在吗？ 修复了@Govind 的问题【参考方案2】：使用此功能
func callDidEstablish(_ call: SINCall!)
let audio = APPDELEGATE.client?.audioController()
audio?.disableSpeaker()
// self.startCallDurationTimerWithSelector()
appDelegate.client?.audioController().stopPlayingSoundFile()
这对我有用。

【参考方案3】：class MainVC: UIViewController,SINCallDelegate
// var client: SINClient?
private let videoController = SinchManager.sharedInstance.client!.videoController()
private let audioController = SinchManager.sharedInstance.client!.audioController()
private let callClient: SINCallClient
private var call: SINCall!
let username: String
@IBOutlet weak var otherView: UIView!
// private var mainView: SinchView return view as! SinchView
@IBAction func call_btn(_ sender: UIButton)
answer()
@IBAction func end_btn(_ sender: UIButton)
decline()
override func loadView()
// view = SinchView()
view = otherView
init(username: String)
self.username = username
self.callClient = SinchManager.sharedInstance.client!.call()
super.init(nibName: nil, bundle: nil)
required init?(coder aDecoder: NSCoder)
print("init(coder:) has not been implemented " + String(describing: aDecoder))
fatalError("init(coder:) has not been implemented " + String(describing: aDecoder))
override func viewDidLoad()
super.viewDidLoad()
call.delegate = self
//self.mainView.videoView.addSubview(self.videoController.localView())
otherView.addSubview((self.videoController?.localView())!)
self.videoController?.localView().contentMode = .scaleToFill
if self.call.direction == SINCallDirection.incoming
self.audioController?.startPlayingSoundFile(self.pathForSound(string: "incoming.wav") as String, loop: true)
if self.call.details.isVideoOffered
print("video offered")
//self.mainView.videoView.addSubview(self.videoController.localView())
otherView.addSubview((self.videoController?.localView())!)
self.videoController?.localView().contentMode = .scaleToFill
otherView.addSubview((self.videoController?.localView())!)
// mainView.answerButton.addTarget(self, action: #selector(answer), forControlEvents: .TouchUpInside)
// mainView.declineButton.addTarget(self, action: #selector(decline), forControlEvents: .TouchUpInside)
override func viewWillAppear(_ animated: Bool)
super.viewWillAppear(animated)
self.audioController?.enableSpeaker()
func pathForSound(string: String) -> NSString
let nsSt = Bundle.main.resourcePath! as NSString
return nsSt.appendingPathComponent(string) as NSString
func answer()
call.answer()
func decline()
call.hangup()
func callDidEstablish(call: SINCall!)
print("callDidEstablish")
let audio = SinchManager.sharedInstance.client!.audioController()
audio?.disableSpeaker()
// self.startCallDurationTimerWithSelector()
SinchManager.sharedInstance.client!.audioController().stopPlayingSoundFile()
func callDidEnd(call: SINCall!)
print("callDidEnd")
func callDidProgress(call: SINCall!)
print("callDidProgress")
self.audioController?.startPlayingSoundFile(self.pathForSound(string: "ringback.wav") as String, loop: true)
func callDidAddVideoTrack(call: SINCall!)
print("callDidAddVideoTrack")
otherView.addSubview((self.videoController?.localView())!)
