Hello when i plug in my headphones in front phanel of my case ( i try different headphoens) there is not anything strange before i open games , while game starts there is some strange buzz or coil whine in background , it happens only while in gaming , what should be the problem ? Also if i put my headphones from back of my case directly to motherboard and not from front panel everything is ok ? Is it possible that that background is coming from the video card coil whine to headphones ?
