I replaced my old Apple TV HD with a newer Apple TV 4K yesterday and have great video but lost the audio. After taking down the wall mounted TV I noticed that the optical output from my TV was not hooked up to the optical input in my Sonos Playbar.
So my question is, how did I get audio from my old ATV HD to my Playbar without the optical connection? The only way it could occur is through the ethernet connection (my entire Sonos household system is wired via ethernet rather than Wi-Fi).
The reason I disconnected the digital optical input from my old ATV to my Playbar is because the optical output from my Sony TV is damaged - the connection is loose. So I would like to again get audio from my new ATV 4K to my Playbar via ethernet again, but I cannot figure out how to do that. All of the documentation I can find about hooking up my Sonos Playbar (it is the older model not the newer one - I purchased it in 2016 or 2017) directs me to hook it up to the TV via an optical cable.
Any suggestions out there? How did I manage to get audio from my old ATV to my Playbar via the ethernet connection? I really wish I had written that down when I set it up like that a few years ago.
