Hi,

I have a SONOS ARC in combination with a TCL 55C715 tv. I have a normal HDMI ARC connection (so not earc). 

I tried every setting but still i do not receive dolby atmos with disney + Or Netflix or Primevideo. . But no atmos on my sonos app

I tried Pass trough, Auto. Enable dolby atmos on tv and disbale but all settings are not working. Any Idea? Or do i need to buy a Nvidea shield for it? 

Maybe this will be a help: https://www.youtube.com/watch?v=T1eSA3MnUvw
