UR12 Setup but no sound

I am a complete AI novice.
I have a Macbook Pro with CubaseAI 10.5 installed
I have a Steinberg UR12 AI. I have installed the Yamaha Steinberg USB Driver 2.0.4
I have connected my UR12 to my Mac via USB cable and have plugged my electric guitar into my UR12, but it does not appear that my setup is correct.
I am not getting any sound from my MacBook Pro and it does not seem like the guitar signal is reaching my CubaseAI application.
Are my expectations incorrect?

Hi Jim
You need to configure the inputs and outputs in Cubase:)
The yourney starts here: Setting up Your System

Good luck and enjoy
