Windows 7 Audio Playback problem, I cant get audio to my tv from computer. How do I fix it?

When I look at my sound playback menu I see 6 options for "Digital Display Audio: AMD High Definition Audio Device Not Plugged in ". No matter how hard I try I cannot get these options to become active and send audio to my TV from my computer. The computer recognizes that the HDTV screen is connected and it sends over video/extended desktop - it just won't send audio. How do I fix this issue? (Graphic Card is AMD Radeon 7950)
