Hi. I have this issue with my G635 too. I dont play APEX but happens in BF4, BFV and BF2042 while in Discord. This never happened before until the BF2042 beta. Dont know if Logitech updated their GHub for that and might have had something to do. Maybe the issue is with Logitech. If I am on Discord and not playing, is ok. When start playing works until some kind of "static" is heard and then no one can hear me. Then I have to Alt+Tab and change Discord mic to C922. ALWAYS. Now I had to enable my webcam mic on discord (logitech C922) until issue is solved.
Not possible that different games from EA are having this issue in Discord with the middle to top Logitech headsets. The thing in common between all this headseats is that they are 7.1 running by logitech. There must be something between EA games, Discord and Logitech softwares that has to be tweaked.
Maybe NVIDIA Experience automatically recording has something to do too. The only thing I have clear is that nothing of this happened before installing the beta for 2042.
Be safe, be cool!!
