Hi

My HTPC has been flawless for years with win7 32bit, a 9500gt and an old pioneer surround amp fed via digital out.  I am building a home theater room and so bought a HD6850 to get DTS-HD etc from PowerDVD playing blurays.

I installed the card and it works fine.  I bought my new onkyo sr608 amp tonight and plugged the hdmi cable from the video card into the amp, and the amp into the plasma.  After getting the resolution right in the control center, i tried to get dolby digital working.  Alas PCM only.  Under the sound tab I can see the ati hdmi output, but the 'supported audio formats' section says hdcp is ok but no supported formats for audio.  The kicker is at one stafe this had a decent list of dolby digital etc, but it has gone.  I have done everything i can think of, reinstalled drivers, used older drivers but I cant make anything show up in the tab.

help please.

Ivan

I had similar issues with my 5670. Install the realtek HDMI audio driver found here

Fixed my issues.

And to enable HD audio via Power DVD you need to play the bluray, and whilst playing right click the video and go into settings and select the non-decoded HD audio in the audio tab. You need to do this each time you play a bluray, other wise it defaults back to DD or PCM

Check that you dont have the reciever set up to allow audio passthru to the display, as that will limit it to what the display can do. Try unplugging the display and repowering the amp and see if more modes come up.
