I just got the Blackshark V2 X headset, and have gone through the setup and registration process to activate the 7.1 option. Device Manager shows “7.1 Surround Sound” as being installed under “Sound, video and Game Controllers”, however when I open the Razer AppEngine interface, the drop down menu does not contain the 7.1 Surround Sound option I need to use the headphones properly. It only has the Realtek audio device, and that does not output any sound to the headphones. I have uninstalled and reinstalled the software several times.
What do I need to do to fix this issue?
