Despite a lot of reading and looking around, I am struggling to understand how to set up with HDMI ARC.
My understanding is that you would have say - an HDMI input into the TV, and then. additional to this from the TV an HDMI ARC connection say to a soundbar.
So effectively the HDMI ARC cable would replace an Optical Digital cable?
So there are still two cables?
Or do I have this wrong, and, if you have a home theatre with the right connections you cable you can get away with a single cable to take the output from that into the tV.. and if its HDMI ARC then the same cable can take the sound back to play through the HT system. Hence you can get away with one cable? But in my soundbar example you would need the extra cable, unless you use something like Samsung Soundshare (if they are both Samsung products) and so do it all wirelessly between the TV and soundbar.
I am planning on wall mounting my TV and just trying to work out how many HDMI cables I need to run into the wall... and if in fact one could be enough?
