I cannot figure out why I have PC audio noise in my speakers when using a per-out amp. So, I have an HDMI coming out of my GTX 1080 graphics card into my LG C9 TV/Monitor. I then have an arc/earc HDMI on my TV going to my Yamaha TSR-700 receiver. When I have my speakers (RP-600) hooked up to the TSR-700... all is well. As soon as I use the pre-outs from the TRS-700 to my external amp (Behringer A-800, and plug my speakers in to the A-800.... their is computer noise coming out of my speakers. Literally, as things happen on my computer screen (like moving a window around) it generates noise that is audible from my speakers. This same thing happened on an older Receiver I had when using its per-outs to the external amp... so I know it is not the receiver pre outs having an issue.
As soon as I unplug the HDMI that is going into my receiver from the TV - or unplug the pre-outs going into the A-800 amp - there is no noise. I have been so confused by this... and again, as soon as I plug my speakers directly into the receiver there is not noise or issues.
I really would like to power the speakers by the the receiver pre-out to A-800 amp, as it has a lot more power.
Also, when I use a fiber optic cable out from the TV the the Receiver, there is no noise when using the pre-outs. As soon as I plug the hdmi from the TV into the receiver, there is noise regardless of input or audio source selection from the receiver..... the receiver can even be tuned off, and the noise is still there.
Any ideas? Or others with is issue? I know I can just eliminate the A-800 amp, but I would really like to use it, as it has balanced inputs too that I would like to use it via a separate Balanced DAC... this way I have the same speakers hooked up to a HIFI music setup, and a home theater surround sound set up. Hopefully this makes since, as it is kinds hard to describe via text.

ANY SUGGESTIONS/ADVICE would be appreciated. Thanks!
