Audition is not recognizing the microphone through my interface

[Miguel22510302l6xm]

Hey yall,

So I'm running on the most up to date version of  Audition as well as the drivers on my Mackie Big Knob Studio. Audition recognizes my interface as a monitoring system as it plays through my headphones and speakers just fine, but It doesn't recognize the mic connected to it. (SM7B > Fethead> Ch1(L) on Big Knob).  Everything is on, the tracks are armed, but nothing. When I go into the routing there is no mic there. Anyone else got this issue?

Are you using the ASIO driver in Audition? Mackie says that the only way you get inputs to show is by using ASIO. It's worth checking out pages 9 and 10 in the manual carefully - I think there may be other curved balls it can throw you too, regarding input/output routing...
