Intel hd graphics on an Asus pro motherboard with realtek hd audio card also on the motherboard, all the latest drivers including bios update, using an Onkyo 9.2 reference av receiver (yep repeater problem)
I tried installing a hdav 1.3 audio card from xonar, this is a top 7.1 channel audio card
I have been tearing my hair out for the last few weeks, speaking to my supplier to great extent, they finally asked me to try another card, unfortunately it was the same result, the Intel hd graphics card had decided my Onkyo receiver wasn't hdcp compliant, so it downmixed my HD master audio to bog standard 5.1,
Now the 'grey' software lets the powerdvd11 play through to my Panasonic Plasma, the power dvd advisor struck up the audio connection as the problem saying it's transmitting as analogue not bitstream.
Finally I decided to do a complete system reboot reinstalling my windows 7 x64, two years worth of work building up my pc specifics and ..... NOTHING!!! same problem
The powerdvd 11 will allow 'uncompressed HD Audio' through to the onboard HDaudio controlled by the Intel chipset, the realtek is there but does nothing, if I highlight the reltek hd hdmi output in 'windows sounds' I get nothing (only has minimal outputs anyway, 2 channel, no dts or dd etc). The tx-nr1007 output shows all formats dd dts hd etc but also shows that HDCP is not supported, arhhh!
I've heard trying a long 1.3 HDMI lead sometimes works, as all my 1.4 leads are only 1metre in length
I'm at a bit of a loss as I built this pc with High definition video and audio as my main goal, and it's failed due to intel's uncomprimising hdcp software, how could it ever supply 7.1 to a two speaker lcd/plasma, a standard setup is through a splitter or receiver, I take it that a third party will end up sorting this out allowing my receiver to get that lovely HD lossless audio it deserves
