Good day. I received the Ryzen Kraken Ultimate headphones on 24.12.... I did not receive the activation code to activate 7.1 surround sound with the shipment. Without such a function, the headphones are absolutely useless to me and I don't know how and where to get the code. Every time it sends me to the page: How to activate and use 7.1 Surround Sound, but there is absolutely no indication of how to formulate the activation key to make it work. Then when I want to write to someone from ryzen, it sends me to the page: 7.1 Surround Sound Code and after I enter the serial number, it writes me this: Your Razer device is not eligible to receive a 7.1 Surround Sound activation code. Please refer to 7.1...... Any help, advice what to do with it? As I already wrote below, headphones without the 7.1 function are of no use to me, and my husband can just throw them away with them.. thank you very much for your help and support. (I'm sorry, I'm using a translator because I work in the CZECH REPUBLIC) Maybe that's the reason why I can't activate 7.1 Surround Sound. Thanks again everyone.
