Razer Kraken TE Surround not working

Hello guys! I recently bought the Razer Kraken TE. The quality of it was great but the surround sound was not so good. For example i cant hear the difference if sombody is above or under me. I also use the THX tournament mode on my right profile but it doesnt work. Reinstalling it was not the solution of it. Are there any other solutions to get it work. I also got a other question, does I need the Razer 7.1 Surround app to get surround sound or can i just use the THX tournament mode on synapse? Every kind of help would be amazing! Wish u some nice christmas days! Patrick
