UMC1820 and Cubase setup

I’m using Cubase 9 Pro, and am using a Behringer UMC1820.

I recently got a Allen Heath GL2400 and and trying to get everything routed correctly.

Got the sound working yesterday.

Today, I’m trying a simple test audio source (i.e. youtube). It pass the audio through the system via the UMC1820 USB cord. Success!

Problem is the next step was trying to open an audio track and get a signal to record. I could do this with my EMU-1212m PCIe card, but I cant figure out the routing to get the audio signal out of the the UMC1820.

Any ideas?

thanks.
