Hi! I decided to start a new thread even if I'm not sure if there are any more users out there who are still struggling with the crazy noises of their X-Fi. Specs: Mainboard: MSI X58 Platinum CPU: Intel Core i7 930 @ 3.81 Ghz Memory: Triple Channel 3x4GB GPU: ASUS Geforce GTX 660 DirectCuOC Soundcard: X-Fi Titanium PCIe @ Windows 7 x64 I have the problem described in the official article of creative: http://support.creative.com/kb/ShowArticle.aspx?sid=24669 It's a subtle (crackling) noise when I'm using my headphones connected to the audio jack of the soundcard. It's the more subtle the less the gpu is working. When I boot my system and just stay on the desktop without doing anything it's very silent but hearable. As soon as I start a browser it's growing a little louder. I'm able to affect the noise by scrolling through websites with pictures. I would say I can hear my scrolling through the headphones. When I start an application which needs a higher performance of the gpu like any game, the noise grows louder and isn't subtle anymore - it grows to a continuous crackling sometimes degenerating when a map is getting load or the gpu is workin on a higher level. What I've done so far: - tried each available driver of the creative Website (driver 126.96.36.1997 produces the quietest noise but not less annoying) - tried PAX and DanielK Drivers following some solution walkthroughs - tried different nvidia graphics Drivers - changed the pcie Slot or the soundcard so it's using another irq than the gpu - lowering gpu memory clock Speed - flashing bios changing cmos - checked if there are any ground Loops - tried Windows 10 - replaced case and power supply - build an emi shield for the soundcard What I can not do: - "Invoke dual-channel memory mode on the motherboard. Systems that are not configured in dual-channel mode can experience crackling during games" - using nhancer to lower the AFR (nhancer doesn't start) The crackling noise is not noticeable when I connect my Logitech Z 5500 via optical cable. So is there anybody out there with similar system specs who found a solution or has any ideas what I should try?
