Help! static noise with Turtle Beach X12

[blackbarrel]

Today I received the Turtle Beach EAR FORCE X12. I noticed when using that there's noticeable static noise when there's no sound, which gets louder when the headset gamesound is put higher. So if you know what's causing this or a solution please tell me! Thank in advance.

Are you using the motherboard's on board audio or a PCI sound card?
