Doubt it was from upgrading to w11, I've had this problem for years before I did a clean install even when Windows 10 was the latest version.

You can try. I did a Windows re-install instead of just uninstalling Cortex. I don't think uninstalling the audio drivers would do anything, but if after uninstalling Cortex doesn't work, then you can try reinstalling the audio drivers.

Here's an update everyone. I solved this issue, but that was by reinstalling windows (the option where you reinstall windows but keep apps, photos, and that kind of stuff). Not sure why this issue happened in the first place, or how to solve it not by completely reinstalling windows.

The mic is connected via USB and the headset is wireless, but still connected by USB. I have tried them both one by one

Hello BlockBuster.
Have you tried this without the discord and any other programs running?

Hi there, I'm having this same issue. When you talk in-game, do you see the mic icon?
