Hi, I got a new computer this week and it has a Creative Sound Blaster X-Fi Xtreme Audio sound card installed and this is connected to the cases own mic and headphone front sockets. When i attach speakers to the sound card directly, i have no issues. When i attach my headset to the front unit (which seems to the ideal way to do it) i get a odd hissing/static noise in game or when i move a window etc in vista. If i am doing nothing there is no issue. So when i am in windows only and move the mouse around the screen there is no issues but as soon as a drag a window or similar it happens. Any ideas how to solve this?
