HP Pavillion Desktop PC
Creative X-Fi Titanium Sound Card
Radeon HD6770 PCIe Graphics Card
After I installed this graphics card I immediately started having a high pitched squealing sound coming through my Peavey amp and speakers. It is there when ever I send any sound from the PC, music or games, it doesn't matter.
I figured that some frequencies generated by the graphics card were being picked up by the sound card, causing the squeal. I thought some shielding might fix that, so I installed a flat tin panel connected to the chassis between the graphics and sound cards, but als, the squeal is still there.
Anybody have suggestions?
