my reply was lost too lol. 2 of the speakers are on either side of the tv and the rear 2 are placed behind the seating position. i found some things that said i can use the tv speakers as center channel, not sure abt the specifics, running a line is not an option due to room position and other factor, could i run center as a soundbar through the existing coax or to the tv to the receiver or directly off the tv - a 2 output kind of thing - ykwim?
My understanding is that for the HDMI to ethernet adapter is that after a certain run ~100ft i need it to be powered. the ones above are not powered as the run is max 65ft. since its only moving audio will a difference of HD, 4k, 8k be audible? the powered ones are like 5 extra dollars online not a crazy price if you say it will make an audible difference to the avg listener.
For the remote issue, I don't have cable, only streaming apps on the smart tv, an apply tv, and bluray player. don't think the apple or bluray need line of sight to work as they are currently mounted behind the tv anyway. as for the tv volume, could i just leave the receiver on like 50-75% volume and "fine tune" the volume with the tv remote? same way when i use car Bluetooth i have phone volume on max and control volume in car with knob on dash?
Thanks, been super helpful. looking forward to your reply!
