DDJ-RX2 No audio when connected to Laptop

I have a new RX2. The drivers are updated on my Mac running Big Sur. I am able to control the decks via MIDI but I am not connecting to audio. I have uninstalled and reinstalled the drivers properly. What else could it be? I'm new to this. I need a response asap. I have to run this system tonight. I'm thinking this is likely a very simple fix.
