I have tried virtually everything to get my HD 4670 graphics card to ouput HDMI AUDIO and still no luck. In the "Playback Devices" screen, the "ATI HDMI Audio" displays "Not Plugged In".
- The audio receiver is connected to the tv via a Digital SPDIF Optical Audio Cable so there is no setting i am missing on my receiver.
- There is no special HDMI input for my TV.
- I have updated the most recent drivers and software as well as completely removing all software and drivers and starting again.
- I have tried disabling onboard audio in the BIOS.
My only concern might be the VGA to HDMI adapter. It is an ATI Rev. A adapter. I bought it on ebay and said it was compatible with the hd 4670 graphics card.
Any help would be greatly appreciated.
