adjusting arctis Nova Pro Headset for FAF

I have a problem with my Arctic Nova Pro headsets while in a game on FAF. I have all setting on normal with NO surround sound turned on. During a game I hardly here anything. This has been going on for over a year now. When I first got these headsets, everything was fine, but one day the sound volume got reduced and I can find no reason for it. The sound works fine for all other cases, including listening to replays. It also works fine in all other games. Can anyone help?

dont run the the software. FA just doesnt work with it properly

How do I NOT run the software??

Especially since it's been installed on my computer for years.

just uninstall it or make it not run on startup. or just close it everytime you run faf
