The Razer Insider doesn't have support for your preferred language. Please post your inquiry or concern in English across all boards. However, based on your thread’s title, I recommend downloading and installing the Razer Driver Clean-up tool: https://rzr.to/Tf53xj. Once done, please restart your computer and perform the steps from this article before reinstalling the THX Spatial Audio app on your computer. Feel free to submit a case to our Support Team or send me a PM, and I'd be glad to assist.
