Every now and then when I play my sound goes nipples up on me. All of a sudden I will get a very very loud and continuous pulsating static noise. Sometimes if I take off my headphones for a few mins and wait it out my sound goes back to normal. Other times I have to restart the game. I cant figure out why this is happening or how to record a sample for you guys to hear. Any ideas guys?
