I added a playbar and two play:1's for a client with some hearing issues. Rather then add the play:1s as rear speakers, I grouped them and added volume control of each speaker via Total Control. This afforded him the ability to adjust the levels individually if desired depending on where he is sitting. This helped him with his ability to clearly hear the dialogue. He emailed me today to say that the zone grouping does not stay grouped when I turns off the TV. He has to go back to the Sonos app and regroup the play:1's with the playbar. Is this normally how the playbar works with zone grouping?

There's an option to ungroup the playbar on autoplay set by default, it should work the way you want it to if that's unchecked.

Thanks, I was not aware of that. I will have to take a look.
