OK great.

You have two options. Option one might work (as I'm not 100% sure about the AVR and its hdmi processing) and option 2 which will work for sure. According to this link your Blu-ray player can internally decode the lossless formats and also supports 7.1 multichannel analog.

Option 1 (HDMI):Read posts 4 and 5.

Option 2 Follow the steps regarding multi-channel analog above (this option will work 100%)
