Question / Help Obs Desktop audio

[stereofox]

So i have connected my headest with my desktop audio device and it won't record anything. No game, no video, it records nothing that i hear. I have tried putting it in desktop audio device 2 but it's the exact same thing. nothing works. I've tried audio monitoring and still nothing. It used to work but now it just doesn't anymore. maybe I have a button clicked or something, I really don't know.
