For the sound recording issue,

Add this code when creating the captureSession

askMicroPhonePermission(completion: { (isMicrophonePermissionGiven) in

            if isMicrophonePermissionGiven {
                do {
                    try self.captureSession.addInput(AVCaptureDeviceInput(device: self.captureAudio))
                } catch {
                    print("Error creating the database")
                }
            }
        })

////////////////////////////////////////////////////////////////

askMicroPhonePermission function is as follows

func askMicroPhonePermission(completion: @escaping (_ success: Bool)-> Void) {
    switch AVAudioSession.sharedInstance().recordPermission() {
    case AVAudioSessionRecordPermission.granted:
        completion(true)
    case AVAudioSessionRecordPermission.denied:
        completion(false) //show alert if required
    case AVAudioSessionRecordPermission.undetermined:
        AVAudioSession.sharedInstance().requestRecordPermission({ (granted) in
            if granted {
                completion(true)
            } else {
                completion(false) // show alert if required
            }
        })
    default:
        completion(false)
    }
}

And you have to add NSMicrophoneUsageDescription key value in info.plist file.
