Got the SBZX a few weeks back after owning a Xonar Phoebus and what the hell happened to Creative ? I am a fan of them but these cards are just awful when compared to the Xonar line up 🙁 Give me the Titanium HD over this new SBZ series any day.

Shame I was getting amazing audio on my SBZ card but now I went GTX970 SLI I get buzzing over headphones when using the SBZ. Seems to be electrical interference over PCIE lanes. I am not running out of lanes as my i7 4770K had 28 PCIE lanes and my two 970s are in 8x 8x mode which leaves me with 12 lanes free. I have tried everything cleaned out drivers, reinstalled drivers, tried different headsets, etc. Nothing works. It got so bad my friends over on teamspeak could hear to buzzing being transmitted through my microphone. I took out the SBZ and installed Motherboard audio and the buzzing instantly went away. I now uninstalled mobo audio and I am using USB headset and it works perfectly fine. Shame, its not my PSU as its a 1200W Silverstone Strider which is more than enough and has excellent specs.

It's soundcards in general they don't really have good EM protection for their mic segments. I had exactly the same problem I just unplugged the mic from the SBZX and plugged it directly into the mic jack on the motherboard and enabled it in the bios but didn't install any drivers, Works like a charm 🙂

Maby try and Install PAX on top of the Creative one drv. Everything working Great on my RIG, and Sound is Exelent + 3D positioning in Games IS way better than other SC ;-) Including Old X-Fi series. I have in my Life -> Gravis Ultrasound (on 486PC ) and lots of SB then X-Fi Extreme Gamer and Now SB-Z But Creative Support for SC Have to be Better, and slowly they gain our trust again
