So I have an ATI Radeon HD 3800 graphics card with an ATI branded DVI t0 HDMI adapter on the back. From there I have an HDMI cable goin gto my Samsung HD TV. I was under the impression that I could get sound through the HDMI cable, but ive got nothing. I read on another post here that you needed the ATI DVI adapter to get sound using the same card I had, so i returned an off brand and got this one. Does anyony have any idea what I can do to get sound to the TV.
