After that update, you’ll be able to change the input in the settings of the SUB. To get there, click the SUB tile in the app. Under ‘Input’ you will be able to choose the following inputs from a dropdown list:
- WiFi/Bluetooth/Ethernet, for the use of wireless connections or Ethernet
- Analog 1, for the use of the RCA pair 1
- Analog 2, for the use of the RCA pair 2
- Digital, for the use of the TOSLINK (optical) port
