Ok so this is driving me up and down the wall. Basically i can only get 2.1 audio from the HDMI adapter i am using on my HD3450. It doesn't matter what the source is. Video works fine. I was then like ok fine i will try using a dedicated sound card for 5.1 sound. But my reciever doesn't like that. Is it because my card is entry level or is it something more insidious. I really don't want to have to buy a new reciever for more connectors (i refuse to use a switch box)

please update HDMI audio driver from realtek site.

737-32277: AC3 (Dolby Digital/DTS) Audio Playback Issues when using an HDMI Receiver



The information in this article applies to the following configuration(s):
  • ATI Radeon™ HD3000 series
  • ATI Radeon™ HD2000 series
  • Grey DVI-HDMI Adapter (Part Number: 6140063500G)
  • Black DVI-HDMI Adapter (Part Number: 6141054300G)
  • Windows Vista 32-bit Edition
  • Windows Vista 64-bit Edition
Symptoms:
AC3 (Dolby Digital/DTS) multi-channel audio which is typically available to end-users who connect their ATI Radeon™ HD2000 or ATI Radeon™ HD 3000 series to an HDMI Audio/Video receiver with HDMI decode capabilities is not functioning correctly with specific software players.
Solution:
  1. Make sure you have the correct setup as below:

  2. On www.realtek.com.tw click on "HD Audio Codec Driver" under Quick Links
  3. Download ATI HDMI Audio Device Driver Version R1.68
  4. Install the driver and restart your system
  5. Open "Control Panel" and double click on "Sound"
  6. Select "Playback" tab
  7. Right click on “Realtek HDMI Output“
  8. Select "Set as Default Device“ (Green Checkmark will appear)
  9. Click on “Properties”

  10. Select “Supported Formats” tab
  11. Checkmark “Dolby Digital” box
  12. Highlight “Dolby Digital” option
  13. Click on “Test” button

  14. Check the display panel of your HDMI Receiver for:
    * Dolby Digital/DTS indicator
    * 5 Speaker Surround indicator
    * If 5 speakers connected, each speaker will have its own sound output


Now you can run your application to play the movie in 5.1 surround (Dolby Digital/DTS):
For High Definition Content:
  • Corel WinDVD 8 Gold or Platinum
    • Right click on WinDVD main screen and select "Setup"
    • Select “Audio” tab

    • Select “6 Channel (5.1 Home Theater)” under “Audio Speaker Configuration”



  • PowerDVD Ultra 7.3 with HD DVD/Blu-Ray Patch
    • There is an issue with this version of PowerDVD playing High Definition content in AC3 (Dolby Digital/DTS). Please contact Cyberlink for support.
For Standard Definition Content:


  • Catalyst Media Center
    • Select "SPDIF" in Audio Settings/Speaker Environment


  • PowerDVD 7.0

I'll also add that you should be using a grey adapter with that card, not the black one. The black one is for 2xxx series, grey for 3xxx. Swap them around and you should even get a msg saying that all audio functions are not available.
