Asus P5E VM HDMI no sound through the TV using HDMI cable

I've recently built a new media PC to go along with my Sharp Aquos 42". The motherboard I am using is an ASUS P5E-VM HDMI, and I'm running an HDMI cable from the motherboard to the TV. I get video just fine at 1080p, but I get no sound whatsoever. I've installed the drivers for the Realtek audio that came with the board and the sound does work fine with headphones, just can't seem to get it working through HDMI and have it come out of the TV. If anyone can help with this situation it would be greatly appreciated, Thanks.

- Jono.

Before running your media file go to Sounds in Control Panel and set "Realtek HDMI Output" as default device. If it still does not work go to properties for "Realtek HDMI Output" and test it under "Supported Formats" and "Advanced". You need to switch it back default to speakers after to get sound back to speakers - I still can not make "smart" computer to do it automatically. Hope this helps - let me know.
