im having the same issue with multiple games too. The one thing that has helped people is going to control panel -> hardware and sound
-> sound -> click the recording tab -> right click the mic you use then go to properties -> click the advanced tab -> turn off the option that says "Allow applications to take exclusive control of this device" then press apply and Ok. After go to the communications tab and press do nothing then apply. That did not work for me so idk if it will work for you, if you do something different and it works, please LMK!!!
