Is the system set to “Full” (not Ambient) when playing music? What sound format does the app say the system is playing when the system is playing TV sound and you get no sound from the rears?

First test is to set Surrounds to “Full” rather than “Ambient”. Then play some music to the room. You should hear it from the Arc and Eras (and Sub). If so you’ve got them set up correctly and may need to change some options in the tv audio settings. Also make sure the tv is playing a 5.1 or Atmos program - many are only transmitted in stereo.
