7.1 Surround Sound Code Lost

Hey I just bought my new Razer Kraken X and I was going to put in the code that came with the box to activate surround sound but I accidently scratched too hard and the actual paper of the code got ripped out and I can no longer see it. I play competitively so this is quite the issue and so is there any way to get another code or see the same code somewhere else that's not in physical form?
