Ground loop problems

Hello, i am having a problem using a blue yeti mic (external mic for computer), a voice changer (morphvox pro on computer), and turtle beach head phones (plugged into xbox controller)

Independently they all work perfectly fine. My problem is when i use all three together people say i sounds like im in a helicopter.

My setup: blue yeti plugged into computer by usb cord. The voice changer is just a program on my computer. And the pink cord of my headset plugged into the headphone jack of my computer. This is how it should work but i am picking up some serious feedback somewhere. Any ideas?
