So I recently added two Era 300s to my ARC for surrounds, which sound great. When I turn my TV off after about 5 minutes it reverts the room to Music. If I try to change it back to TV it tells me that there was a problem and it couldn’t detect a signal from HDMI to the Arc. Once I turn back on the TV it either starts to work again or I have to use the app to repair.
Setup:
Sony 90J TV
Arc via E-Arc port
Sonos Ge3 sub
2 Era 300 set to Surround
External Devices:
Xbox Series X
PS5
Switch
Steam Deck via a Dock
Any help would be appreciated.
