Volt 276 - AmpliTube set up problem

[MilesBarken1000]

I just got a UA Volt 276 and I've downloaded AmpliTube. In the AmpliTube settings input, I have Volt 276 selected, same for output. I'm monitoring with my headphones plugged into the Volt. I can hear the direct guitar signal plugged into input 1, but I can't get hear the signal after it's processed by AmpliTube. Why isn't the signal going into AT or why can't I monitor the AT signal? It seems pretty basic, and the options are limited, but I can't figure out what I'm doing wrong. Please help!!! Thx

I do the hear the click through the Volt and in my headphones, so I'm getting signal out of AT and into Volt
