Hello. I have this problem where sometimes when i do something on my pc for example i open a game i start a video or simply just start a skype call. A VERY loud scrathcy noise begins and i can't stop it so to make it go away i need to restart my pc. I don't think it has anything to do with my headphones nor my soundcard. Because i also had the problem when i used my old headphones and my onboard audio. ( i currently have the ad700x and a soundblaster z ) Do you have any...
