Audio plays through ear speaker

[Ryan-Liebregts]

Hi,

Absolutely love your work here.

I am just wondering if there is any way to make it play through the iPhone's bottom speaker and not through the ear speaker?

Believe it relates to the way it handles the configureAudioSession()

private func configureAudioSession() {
      do {
          let audioSession = AVAudioSession.sharedInstance()
          try audioSession.setCategory(.playAndRecord, options: [.defaultToSpeaker, .allowBluetooth])
          try audioSession.setMode(.videoChat)
          try audioSession.setActive(true, options: .notifyOthersOnDeactivation)
      } catch {
          print("Failed to configure AVAudioSession: \(error)")
      }
  }

Cheers

I've played around with the audio session but wasn't able to make it play through the bottom speaker - if anyone figures it out do let me know!

The Google WebRTC library is overriding the default audio session.

Add a listener to AVAudioSession.routeChangeNotification.

Then do something along the lines of:

  let currentRoute = AVAudioSession.sharedInstance().currentRoute
  if !currentRoute.outputs.filter({ $0.portType == .builtInReceiver }).isEmpty {
    // WebRTC owns the audio session and likes to switch to headset speaker rather than speaker
    try? AVAudioSession.sharedInstance().overrideOutputAudioPort(.speaker)
    return
  }

However, I think you'll find that then the assistant will be hearing itself and iterrupting itself quite a bit. Recommend you crank the turn_detection threshold all the way up. Even then, it can be iffy.
