There is a static noise in my headphones. I looked up what might be causing it and some cords may be the issue so I untangled my headphone cord and pushed away all the cords as far as I could. It made the static a little more quiet but I can still hear the static. Also I'm using a sound card because the audio jack in my motherboard stopped working and I don't have anywhere else to plug in my headphones.HELP PLEASE
