I have a Toshiba CT-8555 TV, Sonos Playbar 1, Apple TV 4K. Playbar connected via optical cable. Apple TV connected to TV via HDMI. I cannot set up my TV remote with the sonos app, it does not recognise it. I have reset the playbar, i have followed the steps suggested - change batteries in remote, turn off the tv etc etc. I can only control the volume of the sonos through the sonos app, not through my apple tv remote, which is the goal. I have the same set up in a different room but with a Sony TV and it all works fine. I am fed up! Please help. I want to control the sound through the playbar with my apple remote!!!
