Streaming audio only from an iOS 12 device is done through the Control Panel on the iOS device. 

  • Open the Control Panel on the iOS device by swiping up from the bottom of the device. 
  • You will see the audio section of the Control Panel in the upper right-hand corner. 
  • Select the AirPlay icon which will open the audio menu which contains all the available AirPlay audio devices on your network.
  • Once your Mac or PC with Reflector 3 is selected you will see the device connect in the menu but the mirrored screen will not appear on the desktop which is indicating the device is connected through audio only.
