Steinberg UR824 and DAW

Hello,
yesterday I got a new Steinberg UR824. I can not configure the DAW routing. I plug in the microphone in input 3 and go to the external device output 3. Audio output appears without DAW on. How do I enable DAW, there is no change. Plugins do not work. Please help.DAW is ProTools or Studio One.
Slav.
