The audio output format need to manually select during BD playback to output as non decoded high defination audio pass through to AVR. This is kind of manual tedious process i don like about it. QUOTE]
Suprisingly last nite when i watch Ironman BD, the DD TrueHD automatically bitsream and and display DD TrueHD at AVR without the manual audio output selection during playback. Will try another movie tonite and see it works the same.
Same here.
First, I did a fresh install of Win7-64.
Then Radeon 5700 drivers.
Then PDVD9Ultra + Patch.
Then Virtual Clone Drive.
But still no "Non-encoded High-definition Audio" option.
Then did the FIX (onkyo 906.inf) which was given on the AVS site.
Then it was a beautiful site.
That infamous "3rd option" appeared and I was bitstreaming DTS-HD MA & Dolby TrueHD.
Then I unmounted VCD and mounted another movie. And it was still bitstreaming HD-audio; I did not have to manually reset the "3rd option".
So for now, I have to conclude that you must use Windows 7 and if your receiver is a Denon (or Sony), you must use that Onkyo 906.inf fix.
Come to think of it, I will also try to see if my ATI4850 card can do the same under the same conditions.
