I got a new PC recently with a Gigabyte GTX 970, it has a small amount of actual coil whine from the card which does not bother me much, BUT for some reason it seems to cause noise through my speakers, for example on Skyrim it makes a buzzing noise that changes in tone when moving, or in furmark it makes a noise through the speakers depending on load, this is only audible when the amplifier is turned up but it bothers me because I do not want the graphics card to damage anything else in my computer or my amplifier, the strange thing is that when I unplug my TV from the amplifier (connected separately via 3.5mm > RCA cable to play TV through amplifier) it stops 90% of the noises and then I can only hear a slight buzzing in one speaker with the amplifier at 90% volume. Is this a faulty card that needs to be sent back or is it something else? I have a Xonar STX sound card in PCI-E x4 slot 3 and the GTX 970 in PCI-E 16x slot 1. WHY is it causing buzzing through my speakers under load and is this a fault or something I can fix and not worry about. I think it might be a "ground loop" which I do not really understand or it is EMI from the GTX 970 interfering with the Xonar STX, which is not very good as the STX is supposed to be a high end shielded sound card... Can anyone help me please. Unplugging my TV input to the amp reduces 90% of the noise but this is not a solution as I now cannot use my TV through the amplifier.
