I recently bought a BDP-93 OPPO player and hooked it up with my AVR 1910. Only the audio goes to the 1910, the video is directly tied to a samsung HD plasma. All connections are HDMI with recent HDMI cable (good for 1080p / 3D).
I set up the audio output of the oppo on bitstream and the AVR1910 input setup to "Auto" and this is what I got:
As long as the movie is not started (menu, movie trailers), the sound is ok, but no HD (the receiver displays Dolby D). when it gets to the movie, the HD blue lights is on, the receiver shows DTS HD MA, but there is no sound. Actually, I can hear the audio if I bump the volume from -15db to the max (+12?).
If I go back to the oppo and set the audio format to LPCM, the sound is back to normal. The receiver says "Multi In" , the blue light is off.
I tried to reset the processor, switch inputs, no luck. I know that other people have had a similar problem before, but I could never find if there was a solution.
