I got my Blackshark V2 X headset yesterday and it came with a 7.1 surround sound code. I tried to scratch it off with a coin, however when doing so, some of the letters came off making it impossible to know what the code is. I've tried a lot of combinations, and none of them worked. If there is a way to get a new code for the 7.1 surround sound, that'd be great.
