Question / Help Arctis 7 Game Setting Gone

[Majia]

I stream on Twitch using OBS. Up until yesterday, my audio settings were all set properly with Mic/Aux 1 set to Arctis 7 Game to capture game and system audio, and Mic/Aux 2 set to Arctis 7 Chat to capture my mic. However, when I opened the software yesterday, the Arctis 7 Game option had completely disappeared from the drop down menus. The audio settings on the computer are still using it and it still works just fine everywhere else in the system except for OBS. It seems that it must be something that changed in OBS rather than a larger system issue, but I can't figure out what might have possibly changed.
