Finally found the app to test the razer headphones but it doesn’t really simulate surround sound much less 7.1 . (that’s control panel, sound...7.1 surround sound speakers, configure….test. one thread suggested to go to properties and uncheck the items under the advance tab, but unchecking “enable audio enhancements”, stops the sound from all ‘speakers’ except left and right.
And yes, the razer appengine 7.1 is running and on. Turning it on only enhances the bass sound, a little more volume, nothing else changes.
