Question

I have implemented sinch video calling in ios swift project i have followed all process given in sinch implementation document https://www.sinch.com/docs/video/ios/#calling. And i am successfully able to implement but i am getting on issue my video sound in coming from front speaker. how can i solve this problem?? Below my code:
var client: SINClient?
var sinCall : SINCall?
Configuring 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

This is how you can manage SINAudioController to manage audio output.
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()
}
try this to manage AudioOutput Session manually
// 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

Use this function
func callDidEstablish(_ call: SINCall!) {
let audio = APPDELEGATE.client?.audioController()
audio?.disableSpeaker()
// self.startCallDurationTimerWithSelector()
appDelegate.client?.audioController().stopPlayingSoundFile()
}
this is work for me.
