Here's the setup. ASUS Xonar DX and Yamaha RX-V571 connected via the speaker out on the Xonar to RCA inputs on the Yamaha. I'm using a cheap, probably not shielded 3.5mm to RCA cable. It's on of those black cables that you get with equipment for free.

When I'm on the desktop or playing a video or music, there is no noise. It's clean. The moment I start up a game, especially the new COD BO4, I get signal noise. The sound is high pitched and will raise in volume if the game doesn't make a sound. New sounds negate the noise and it starts up the process of going from quiet to loud. During gameplay it isn't a problem because there's new sounds all the time.

The sound only exists when connected to my receiver. I've connected my ATH-A700's directly and there is absolutely no noise. I like to run my headphones through the receiver as an amp for my cans. I have Beyerdynamic DT-770 pro 250ohms that I like to use.

So my question is how do I resolve this noise? Upgrade my cable? Add ferrite chokes to some existing wiring? Thank you ahead of time!

I figured out how to eliminate the sound. I had to unplug almost all of my hdmi cables. The one connecting my video card to the receiver, the one connecting to my projector on the other side of the room and the one to my PS3. The one to my Roku didn't make any difference.

Any ideas of how to fix my problem? New HDMI cables with ferrite chokes?

It might help to have the PC and receiver power cards plugged into separate surge protectors
and plug each surge protector into separate wall sockets.
