Problems with Input and Output settings

Good morning guys, I’m an Italian girl. The next year I’d like to attend to the Conservatory in Milan. In this moment I’m joking with Cubase installed on my Mac Book Pro and I’m not able to hear anything from outputs. As you can see in attached snapshot inputs and outputs are NOT set. How can I set these Input/Output? Please give me some clue. Thanks a lot
