I recently tried to group a Playbar with Ones and a Sub in one room and an Arc with Ones and a Sub in another. After the grouping process both show the added speakers as “Room(+?+?+?)” next to the Playbar and Arc. I suspect it has to do with the last screen during the set up process which stated the following:
Audio setup problem
Your sound can’t be optimized right now. You can tune your products later in the settings for this room.
I had no issues setting up the Playbar and the Arc. Anyone else experience this issue and have a solution? It’s quite frustrating!
