I have a 52LG70 tv that has 4 HDMI inputs and a Yamaha receiver with 2 HDMI inputs. It is fine for now because I only have two devices hooked to it so I have them both in the receiver and an HDMI from the receiver to the tv. If I get more though, I would have to hook the additional HDMI's to the tv directly, but what is the best way to get the sound to the receiver? Should I hook an optical cable from the tv going to the receiver so any sound coming to the tv will be directed to the receiver? Or would it be better to run the HDMI to the tv, and maybe an optical from the device to the receiver?
