I have a Bose v30. I just upgraded from a Samsung 55LcD and purchased an LG 65CB Smart OLED tv. I have many components as well: a PlayStation, XBox, and Apple TV. I would like to figure out how to use the smart tv functions like Netflix from the TV and listen through Bose. I was hooked via HDMI to the Bose. Now is the same. I use a Logitech Harmony One remote.
I would suggest you connect all the external sources to the TV with HDMI.
Connect the TV audio output (probably optical) to the Bose.
This way you will use the TV to select the source and the Bose will do the sound for everything,
You will need to reprogram the Harmony One for the new TV and new hookup scheme.
