No HDMI audio output to TV

Sup guys,

I got a Dell XPS M1530 that will display video perfectly fine through HDMI, but it will not play sound through HDMI. It says HDMI is ready but when I test it there's no sound coming through. I've tried setting it to default and still nothing happens.
Here's a screenshot of my audio settings. http://imageshack.us/f/51/c1d.png/

  1. What type of video card do you have?
    It may just be a driver issue.

    nVidia 8400M GS. I've installed the latest drivers. It says there should be a set up digital audio option but there's none there. I've previously had it work on my older hard drive.
  3. I've also tried many drivers from Dell and nVidia, none seem to work.
  4. I've just tried using this discs that came with my computer, no luck either.
