This would lead me to believe that either my Bluray player is not correctly sending the correct signal to my processor. I know very little about the difference between Bitstream or PCM and hiope that maybe someone out there can tell me what i am doing wrong? I am running HDMI 1.4 cables and both my processor and Blu Ray player have the latest firmware.
How can I get sound from my rear surrounds?
It would be good to confirm the operation in both PCM and bitstream modes. Normally the sound quality is identical, but when bitstreaming the AV processor has to do all the decoding, so it shifts the burden there. What does the UMC-1 display when playing the 7.1 track, does it say 7.1?
Bitstreaming also prevents any interactive menu or commentary sounds from being heard. That can only be done if the audio is decoded in the player.
This choice is controlled in the player's audio setup menu. When selecting PCM for the HDMI output, make sure that Secondary Audio is turned off, so that the lossless soundtrack will be heard.
Do you have any other 7.1 discs on hand, like Toy Story 3? If so, you can see if the sound comes out the rear speakers, and you can try the calibration tones there to see if they have the same issue.
