Just leaving this for everyone as I got it to work..

Call this right before setupSession()

func setupBackgroundAudioPreference() {
        do{
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord,
                                                            with: [.defaultToSpeaker, .mixWithOthers ])
            try AVAudioSession.sharedInstance().setActive(true)
            session.automaticallyConfiguresApplicationAudioSession = false
        }
        catch {
            print("Could not set audio preference..")
            
        }
    }
}

@danieldelouya any other recommendation? It's strangely working for me the first time I open the camera but not the second one.
