Since the Games recording doesnt work i want to help, here is information about my pc:
Windows 11 Insider Preview Build 26020
As Speaker mainly: Logitech G935
As Mic: Tonor Q9
I tried it with the Headset Microphone and with the Logitech Hub fully closed through task manager but it doesnt record anything. Yet when i turn on live mic i can hear myself, but the game doesnt record it for whatever reason ¯\_(ツ)_/¯
