Ever since I changed my headset to Razer Orca and reinstalled windows, I've been having static sound issues. The static doesn't appear unless I open up a game or some sort of a program. For example: if I open up foobarr, you can almost barely hear the static there, however if I decide to scroll, the static gets louder until I stop.
When I launch Star Craft 2 the static becomes constant. The static sound is very thin. You can hide it with music, but it gets annoying very quickly if you play without music. Also, right now watching MLG the static appears but for a very small amount of time.I have tried my headset on my friends PC, it was fine. Also, tried two different headphones, ones which I bought few hours ago, the static remained. I have installed the firmware updates for sound, however, there doesn't seem to be a sound card in my PC.
