My setup: PS3 and Computer connected to Samsung t240 Touch of Color HDTV, PS3 via HDMI, computer via DVI. I have my Bose speakers currently plugged into my computer, but I also want to play my TV though the speakers as well. When I use the headphone jack on the side of the TV and put it into the input port on the Bose control pod I get a ringing noise, I've tried 3 separate cables, same result. What would be the cause of this and how would I resolve the issue? Thanks
