No sound over hdmi to tv - 5770

I've just connected my plasma to my computer via hdmi. I am not getting any sound.

I would assume it is the one on the bottom, but testing does not generate any output.

Please help.

  1. Sometimes you have to install the HDMI Audio driver seperately. Go to the ATI.com website and search for the "HDMI Audio Driver"
  2. They are only drivers for windows xp. I'm running 7 64 bit. Should I need a driver?
  3. Make sure you go to Control Panel > Hardware & Sound > Sound right click in the box that shows all the devices and make sure "Show All Devices" & "Show All Disabled Devices" are checked. Once you've done that you should see "ATI HD Audio Output" and make sure you enable that. That should take care of it.
