I just recently put a GTX 970 in my main rig, and ever since, I've been getting buzzing/static/interference coming through my receiver (refurbed Onkyo TX-SR507), but only when the GPU is being used. While on the desktop, there's no static/interference at all, but as soon as I bring up a game, (or really anything that stresses the GPU at all), the static starts occurring immediately.
Few odd things that I've noticed when the static occurs while the GPU is under load:
I do have a second receiver (Denon AVR 790) close by that doesn't exhibit this behavior, but that receiver is used for my main home theater setup, and I'd rather not use it for PC use.
Seeing as the static is occurring only when the GPU is under load, and even when there is no connection of any sort between the PC and the receiver, I suspect that I have either some sort of ground loop issue or EMI/shielding issue on the Onkyo receiver. I've tried connecting the receiver and PC to different outlets, but no luck.
Anyone have some ideas?
Few odd things that I've noticed when the static occurs while the GPU is under load:
- The static from the receiver occurs even when the computer is not connected AT ALL to the PC. I normally have it connected via an optical cable from my PCs sound card, but unplugging the cable, or even switching to a different input on the PC, does nothing to quell the static.
- The static will subside for a moment whenever I connect/disconnect the optical cable from the PC to the receiver, but then immediately starts again a second or two later.
- The static is most noticeable through my headphones, but can still be heard from the speakers connected to the receiver.
