Cant get Audition to work with my interface.

I have tried to connect my microphone through two different interfaces (Focusrite Solo and Steinberg UR12) into two different brand new computers (HP Elitebook 840 and Acer Nitro 5) but I have not been able to get my studio microphone to work with Adobe Audition CC 2018.

Here's some details:

The computers can see the mic and I can see levels moving on windows sound settings. I can also hear the test tones on the playback side of windows.

The latest drivers have been downloaded and confirmed to be working correctly.
I can hear the microphone through the interfaces just fine and audio played back from Youtube and other sources sound fine.

And here's the thing: Audacity sees and records audio just fine. I can even record in Audacity and export it into Audition and edit the file just fine, but I cant record from within Audition.

Through my Sherlockian powers of deduction, I conclude that Adobe Audition is the problem... But what is the problem and how do I fix it?

I've dug through the Audio Hardware settings and I've tried both MME and AISO settings. I've also tried a third party ASIO driver (ASIO4ALL)...

But still cant get Audition to recognize the microphone. There are no error messages, just no input at all when I record.

Does anyone have any idea what the Hell I'm doing wrong? Is it channel mapping? I dont know what I could have done differently.
