Cubase AI - No mic signal detected.

Hey guys! So, im a newbie when it comes to studio softwares. Just got my first USB Audio Interface ( Steinberg UR22 mk2 ). My problem is that im not getting any mic signal. My guitar works fine, im getting a signal there no problem. And my midi keybord works too, But im not getting any signal from my mic. Im pretty sure that I have everything connected right because everything else is working so my problem must be in the settings. So do you have any tips for me where to start looking for the problem? Sorry for the stupid question, but help a noob out so I can start making some music!

Thanks!
