Force group Sonos Port with another Play:5

If you click on autoplay room, what does that screen show?

User573051,

I suspect you are perhaps having this issue, because you appear to have two Sonos “Rooms” with the exact same name of “Living Room” showing in your screenshot above … what are each of those two identically named rooms?

Can you perhaps rename one of them in “Settings/System/[Living Room]” so the system can tell them apart from each other and see if that resolves the matter?

Also can you clarify if you use Amazon Alexa with your Sonos setup, as that too can have an effect on auto-grouping/ungrouping your Sonos rooms through a thing called “Amazon Alexa Groups”.

In fact, you are pointing to something that was unclear to me about rooms: I have my Port and my Play:5 in the same room (that’s why I want to force group them) but it looks like room = one device only. Is this correct?

I do not use Alexa.

Yes, give the Port and Play 5 different room names … that should hopefully solve your issue and stop them ungrouping.

As Ken is suggesting, names in Sonos are speaker identification, not physical location identifiers. You could easily call the two rooms Peter and Paul. I’m not sure how the Sonos software works exactly, but changing the room names would be a good test. 

In my home, some ‘room’ names are the room, but in some cases, I’ve just used the type of player. I know that the room named PLAY:5 is my guest room, or Sonos One is my bathroom. That also helps me identify what speakers I’m using when I use AirPlay 2. 

Works perfectly now. Thanks.

Interesting. I’ve always assumed Sonos ignores names, and uses speaker IDs in the code.
