Not sure about the HDMI(computer) to DVI(TV), but DVI(computer) to HDMI(TV) does allow sound. You do have to connect a SPDIF cable(small 2 wire cable) from the motherboard to your video card.
@BrianHartung:As it turns out this also happens to my IE, FireFox and Outlook. Where it list those programs under image and the previous address under Address. I have run all kinds of scans, even scanned for rootkits.
