Mic problems - Xbox One w/ series x/s controller

Microphone inputs won’t go through in game or in party chat when the headset is connected to the 3.5 mm headphone jack on the series x/s controller with the keymander 2 on Xbox one. Game sound still works with my headset and i’m able to adjust audio settings like mic monitoring, chat mixer, and volume, but the microphone will not be detected when the controller is plugged into the keymander. I’ve tried everything I could think of: restarting the console, resetting the keymander, using different headset, using different controller, unplugging and replugging everything, swapping cables. Nothing seems to work. Any suggestions?

P.S: I’ve had the keymander 2 for several months and this has only happened once before. However the first time the mic started working again in a few minutes after restarting the controller and keymander. This time, it’s been a few days since the problem started and the mic hasn’t started to work again.
