My new HTPC and 5.1 Audio over HDMI

Quick question for you guys. I recently built a new HTPC. Nothing too special. 4GB RAM, 550w PSU, Reagor 250 CPU, and a 5450 ATI video card. I have been having one hell of a time trying to get 5.1 output to stream to my 47 inch TV over HDMI. I guess it is possible, but for the life of me, I can't figure it out. I can get 2 channels to show up in Windows 7 32 bit, but nothing more. Check out my screen shot.



Any ideas, please feel free to spew your thoughts here!

  1. Try installing the Realtek 2.39 ATI HDMI audio drivers and see if that helps. You can find them on the Realtek website. Be sure to only install the 2.39 drivers, not the 2.41 drivers. They're under the ATI HDMI audio, about 2/3 the way down the table.

  2. Have you installed the latest HDMI audio driver from the Realtek website? It is separate from the video driver.
