Audition Audio Channel Mapping not showing all my speakers for 5.1 anymore. (Realtek Drivers) Win10

Hi, I was able to connect my Yamaha Natural Sound AV Receiver RX-V371 to audition and have it pan all 6 speakers for 5.1

Not too sure what happened but I got it working the other day and I got a notification out of no where that my hardware settings had changed and now it wont play back or solo on the Center, LFE, Right and Left Surround. 

When it was working I had the audio hardware set to Speakers (Realtek High Definition Audio) and my windows 10 sound was set to Realtek Digital Output (Realtek High Definition Audio)

In the audio channel mapping tab it had realtek high definition audio 1-6. Now it only has 2 for the Left and Right.

I have photos of what the settings were when it was working below.

I've talked to customer service from Adobe and from Windows 10 and they couldn't figure out what was wrong. I've updated my drivers and tested rollbacks. I've rolled back to different versions of audition like 13.0 and others. Last time it was working was on the current version of Audition 2020 v14.9

Let me know if yall have any suggestions.
