I had the same ploblem with sound , but I got other problems with 3D apps that are not games. Unable to open stl or ply files, refreshing of windows piling on the top of each other, a nightmare before finding the problem. So I just stopped/deactivate NahimicService, and the result is instant. You restart your programs and all goes well. Win10 2004, last version of Nahimic on 2020-04-26
