What's your brand of AVR? Some of the entry level early AVR's with HDMI connections did not pass audio through HDMI, only the video. If this is the case allowing the player to decode the audio will NOT work either because the AVR would not be able to pass audio through HDMI.
If your receiver has 5.1 or 7.1 multichannel analog connections and so does your Blu-ray than you will be able to receive the lossless codecs such as DTS Master-HD and Dolby True-HD.
You would need to run 4 pairs of these cables (7.1) OR 3 pairs for 5.1.
