This thread is an absolute mess. Between the obvious language issue ( I suspect some here don't speak English nativity so they rely on google translate or other), and the lack of actual information, nothing is gained from this. Let me help you all out.
I actually have this sound card. Purchased it from my local shop here in Ontario, Canada (Canada Computers). Installed it on the top PCIE x1 slot on my motherboard. I didn't bother with the RBG as I find that it's nonsense. Went to the creative website and downloaded the latest driver and software. I can whole hardly say that I have never had any issues with this at all. Created my own game profiles, set it to 7.1 surround, everything is crisp, clear, no static, no feedback.
I'm not an audiophile at all, but I paired this with some budget Samson SR850 headset and it was 100000% better than the onboard and the old headset I was using (Plantronics Rig 500 HD 7.1).
If anyone needs validation, I can snap a pic of the sound card in my case as well as a screen shot of this thread with the Creative software.
