I recently got a 2012 Mac Pro and have Windows (boot camp) installed on a second partition. When I have the Mac hooked up to the TV via HDMI cable the audio comes through fine on the Windows side but I can't seem to get it working on the mac OS. When I go into Sound in the System Preferences the TV doesn't show up under output so i can't select it there. Does anyone have any idea how I can resolve this? It's pretty frustrating.
