No Audio Input - Behringer x1204USB mixer input/output

[fredphoesh]

Hello people,
I have my new Behringer x1204USB connected, can play PC sounds, and I can record my voice via mic plugged into the mixer on Adobe Audition, but on Reason I see only No Audio Input.
In Preferences... I see the Audio Card Drive (mixer) listed there and has a green tick. Set to 48k (native for the mixer)
Manual Monitoring
But I get "No Audio Input"

Any ideas? Tx
Mark.
