I have an Apple TV 4K, a Sonos Arc, a sub gen 1 and two play 5s gen 3 and a Samsung smart tv with an arc connection but no e arc connection. I purchased a hd Fury Arcana to get Dolby Atmos from the Apple TV. The Arcana is connected to the Apple TV, the outputs from the arcana go to in the case of the arc connection the Sonos Arc and in the case of the HMI connection to the Samsung TV. For some reason I get no sound out of the play 5s (the rear speakers on the home theatre set up) either from the tv or for music - any suggestions as to why this might be?
