I believe that the PS3 audio connected thru optical defaults to send regular DD 5.1 audio from the BD. Do you have multichannel audio "on" or "off" for your PS3? If you have it on, the BD could think your HDMI is connected to your AVR and could be sending audio down your HDMI, but since your TV cannot decode any audio, nothing gets sent out thru your TV speakers. Just a thought. However, I still stand by my previous statement that DD 5.1 just automatically sent out via optical...which is why all your other BDs work. If you try this on a "TrueHD" receiver via optical, the light which tells you the "TrueHD" processor is running won't be on.

As long as all the music, dialogue and commentary are all encoded in DD 5.1, then you'll be fine with just optical output.
