The audio optical in from the television to the player would probably be the easiest and ideal for that setup.
Just a heads up - the optical audio will only send a stereo (2.0) signal from all your devices, since the optical port in the television isn't a pass-through, but instead transfers the audio to 2.0, regardless of HDMI signal.
This is all new to me but I have a question. I just purchased a Samsung Z410T HTIB system. I have a Samsung LN46A650 TV, I have 3 devices hooked to this TV and they are:
Samsung Blue Ray Player via HDMI
HD DVR Box via HDMI
Xbox 360 via HDMI
What would be the easiest way to get all 3 of these devices hooked into the Z410T receiver for the audio?
Thanks in advance.
