I have a 9 month old pc. I built it myself, it has worked fine for 8 months. Over the last month, the headphones have gained a high pitched whine. There has always been some static, but it is unnoticeable when other sounds are playing. However this high pitched whine hurts my ears. It also persists when the headphone is unplugged even though the static cuts out immediately. After leaving the headphones themselves unplugged for a week, the whine disappeared. It reappeared within seconds of replugging it in.
All my devices are plugged into the same powerboard except the ethernet cable. The headphones are connected through a soundblaster 5.1 omni external sound card, and the soundblaster itself is plugged into the back of the computer directly. I recently managed the cables so no cables seem to be touching. I don't mind the static at all, I specifically want to eliminate the high pitched whine.
