Can't register 7.1 surround sound

Which headset do you have exactly? Some of them comes with scratch card in the box, some you'll need to register with your Razer ID, and you'll reveice it by e-mail:

• Razer BlackShark V2 X (RZ04-0324) - Scratch card
• Razer Kraken (RZ04-0283) - Product registration
• Razer Kraken X (RZ04-0289, RZ04-0295, RZ04-0296) - Scratch card
• Razer Kraken V3 X (RZ04-03750) - Product registration
• Razer Base Station V2 Chroma (RC21-0151) – Product registration
• Razer Barracuda X (RZ04-03800) - Product registration
• Razer Kaira X (RZ04-0397) - Product registration

Once you confirm that your headset is 7.1 SS compatible, try using English US keyboard format when typing in the activation code. We have seen in the past where other English keyboards do not work. Otherwise, wait for one of the RAZER official support to be in contact with you through this thread. Prepare the followings~~~

• Name
• S/N
• P/N
• Proof of purchase (legal receipt)
• Email address &/or RAZER ID used for registering your RAZER product

Alternatively, drive your hearing senses through the roof by upgrading to THX Spatial Audio. Most latest RAZER headsets are compatible with THX Spatial Audio. Check it out by clicking the following link~ https://www.razer.com/p/RZ11-13000-0001
