I have a new TV that has 2 HDMI input ports but one says HDMI ARC. I understand that ARC is supposed to be 2 way but here is where I get lost. Since the sound is not very good I wanted to add a sound bar (possibly). Right now I stream Internet through the ethernet cable to the TV, have Direct TV on HDMI 1 and my Blu Ray on HDMI 2. Since there is no AVR that means the only output that I have for a soundbar is the Optical outlet which means I would either have to connect to a optical in soundbar or get a digital to analog converter and hook it to an old stereo system.. The only other option that I can imagine is to connect the D* and blu ray to a HDMI switching device and connect these to HDMI 1 on the TV which would free up HDMI 2............But since HDMI 2 ARC says INPUT on the TV , then how can it be an output to send all of the signals from the internet, Direct TV, and Blu Ray to a sound bar that uses HDMI input.????? Also would the sound bar's volume be controlled by the TV remote or should it have it's own separate remote (which would mandate a viewable volume bar)?
