I connected my TV as a second monitor to my desktop, but I'm not getting any sound over HDMI. My first monitor uses DVI. I have the latest Nvidia drivers. I have the default audio output set to the TV connected over the HDMI (Its shows my TV's name and says Nvidia High Definition Audio). The audio bars move up and down when there is sound, but nothing comes out of my TV. When I plug my PS3 into the same HDMI port on my TV the sound works fine. So I'm guessing it's an issue on the computer side of things, but I'm not sure what. Any ideas?
