App doesn't recognize or display Sonos grouped speakers

Issue description:

Android 14, Pixel 7a. I have a number of grouped Sonos speakers. For example, two Sonos Ones in a stereo configuration with a group labelled, Kitchen. The problem: the app cast screen shows all my devices broken out seperately. So I see my two Sonos Ones (R & L), but nothing about their group (Kitchen). I tried to choose one speaker, thinking perhaps Sonos would take over and play the group, but instead I get a string of error notifications from the Symfonium app and it shuts down all playing. I have exported those error logs via the app. I am able to successfully cast to my Beam and Arc soundbars respectively, and that casting happens immediately.

It seems that they do not advertise at all as UPnP on your network.

Are those recent groups created with the last version of SONOS app?

I think there’s no some settings to enable UPnP on the groups.

Yes, those groups were created with the latest version of the Sonos app. FWIW, Plexamp, Spotify, and Tidal display the groups and I can cast to them.

Could you clarify your last sentence about settings and UPnP?

The other apps don’t use UPnP but the shitty limited cloud protocol.

Sounds like the groups are not properly updated by Sonos :frowning:

@Sanizzle how did you create the groups for them to be visible in UPnP ? Do you also use the last SONOS app version?

Does this mean I’m out of luck? I’m not super techy but it sounds like there’s nothing I can do on my side?

I only have 1 SONOS left so no group to test but @Sanizzle can play on groups without problems so he maybe can give some light on what he did differently for the group to be proper on UPnP.

Hi guys,

I created the group with the S2 Sonos app indeed.
And I can tell you that it is very hit or miss…

As you know I had this problem with the ARC + 2 ERA + SUB, and I had to ungroup and regroup to make it work.

But during this process I also tested the 2 ERA as a stereo pair, and It had the same behaviour of showing not just one pair (group) in the Symfonium App, but 2 separate devices, although the group was visible in the Sonos app, Spotify, Tidal, Plexamp…

I chose one of the device ERA I could see on the Symfonium list, and the sound cale from only one, not the pair. Same for the other one.
I tried later and nothing came out.

I decided to ungroup and regroup again, and it worked fine.

I finally regroup the whole ARC + ERA + SUB and it worked, but I really can’t explain why, since I didn’t do it differently than before…

Sorry if it doesnt bring you a true method to follow but I can only advise you to ungroup and regroup several times until it work.

Thanks for the info and it sounds like I’m having the exact same experience. I’ll give that a try but it definitely feels finicky and not a total solve. @Tolriq are you the dev/founder? Is this something you’re looking at addressing?

Unfortunately there’s nothing to fix on my side.

The new sonos app is bugged as hell, just check all the forums and complains.

Their other API is very limited, bugged and cloud based and the reason why apps using it have often issues (except the big cloud company like Spotify with special integrations)

The Symfonium UPnP integration work pretty well now.

If they do not expose the proper data to UPnP I can’t invent it.

I’ve been enduring the Sonos debacle too. It’s awful. Well, thanks for the ideas and back and forth. I’ll see how it goes.

No problem, hope you’ll be lucky.
@Tolriq is right about all the Sonos bugs, those last months have been a Nightmare, I wasn’t able to access my library from the Sonos app for weeks… The workaround was through Plex but wasn’t perfect and I finally had troubles with playing FLACs… Hopefully they stabilize this.

Let us know on your side

Update: tried ungrouping/grouping. Tried removing speakers and re-adding. Tried turning everything off and on again :smiley: No luck for anything. It’s a real shame because I really like your app, but my primary use is casting to Sonos. It’s unbelievable how they badly they fouled up their ecosystem.

You can still ask them WTF they are doing on their support forum and how to have the groups back properly via UPnP.

For sure. Although they’ll probably just tell me it’s my wifi connectivity problem /s

I’m new to Symfonium but have used Sonos with BubbleUPnP for a long time where it’s never displayed any Sonos groups, instead I have to make sure that I play to the master speaker (the speaker you click on in the Sonos app to initiate group creation) in order for it to work correctly.
I’ve just tested this in Symfonium with a pair of Play 1’s and if I play to the slave the sound comes from only the one speaker, whereas if I play to the master it comes from both.

That seems to be the way. I cast to my arc and then just use the Sonos app to pick the speakers I want. That saves me picking the wrong main speaker in my other paired groups and getting app errors.
