On the back of the Sony TV there is two HDMI connection ports stacked one over the other. Above the top HDMI port has "HDMI In". I have a HDMI cable running from my Sony Blu Ray DVD player to the Denon 3808CI A/V receiver, then another HDMI cable running from the Denon A/V reciver to the Sony TV. I am not getting any sound from my home threater speakers when watching cable or network channels.
