I've got a BenQ W1070. It has two HDMI ports on the back of it. I use one of them for bringing video from my bluray player into the projector. Can I use the other one to bring audio out of the projector and into my surround sound system (which has 2 HDMI-in ports)? I've read through the W1070 manual and it never mentions that second HDMI port or if you can send audio back out of the projector, so I thought it would be safer to ask first before trying it and possibly doing damage to something. I also can't seem to find any info via google regarding using one of those ports for audio-out.
A little background info on why I'm asking this - the bluray player (a Panasonic DMP-BDT360) only has one HDMI port so I think my only option is to run audio that's fed into the projector back out of the projector and into the surround sound. I've been using an optical audio cable for sound up until now but the bluray player seems to have something wrong with its optical-out port and sends popping/crackling noises to my surround sound, so my only two options now are to buy yet another 3D bluray player (I'm on my third - they always have some kind of problem) or to do what I'm asking about with the HDMI ports. It would also be nice to take advantage of the HD audio I've been missing out on with my optical audio cable setup.
