UE4 and Speakers interence

Hello. Finally i want to known why, Its a bit annoying and very strange, when i moving the camera in the viewport i hear a noise/interference/static in my speakers.

Not problem in standalone or intensive GPU usage like VR.

I google it and other have same problem but not any solution.

I not remember have that problem with other application or game.

What’s your GPU set-up?

i have a AMD R290 with latest stable drivers and ASUS H81M/i5-4570
