Razer Kraken 7.1 Chroma Help

Hello, I recenltly bought a new Computer to play Cyberpunk. Since I owned a Razer Kraken 7.1 Chroma I wanted to enjoy Cyberpunk with 7.1 Surround sound. Unfortinatly I could not find the packaging and manual anymore and since I never applied the code, 7.1 surround sound is still locked. So, long story short: is it possible to get / buy an activation code for my Headphones w/o buying new ones? Thanks for your help. Peter
