So, the receiver has several speaker connections, it also has an optical port, which I know the receiver has as well. I also tried to use a coax connection and that doesn’t seem to work either. I am trying to hook my BD player, an Xbox, plus the tv...then connect them all with the hdmi out port to the tv??? This is driving me insane as I am someone who can typically knock all this out in a few minutes with some help just to pick up the heavy things, but I did all the hookups. Arghhhhh
