Here are 3 things you can try:

1. Go to your audio setting and under “Headset chat mixer” turned it all the way down. Seems theres a bug that flips the levels for whatever reason hopes that helps![br]

2. Try restarting your xbox then when it turns back on re-sync the controllers via the bluetooth button the plug the mic in, very frustrating problem but this worked for alot of people, Hope that helps someone![br]
