Spotify connect with Sonos

If you force close Spotify app and reopen, do the other Sonos rooms then appear as options?

Thanks for your response - No they dont, no matter what i try, rebooting wifi, deleting my sonos system and starting again did also not work, just cant understand why… only when i play a track in spotify on my connected device such as my phone and then go in the list will my sonos arc will appear on its own, i then select that which works fine but still none of the other 2 devices show, i add them add to the group through the sonos app and the spoitfy will show Arc +2.

I stop music playing, force close the spotify app closed and reopen and the Sonos arc has disappeared again from the list. 

What is your network setup? Are the other rooms connecting to extenders or different nodes to the Arc?

Hi Mr T, no extenders or mesh nodes. Everything connects directly to the same Plusnet router.

One thing that may be relevant is that I’ve previously had difficulty connecting the Sonos speakers during setup because they connect on 2.4GHz, while my router uses both 2.4GHz and 5GHz under the same network. I’ve previously had to temporarily disable 5GHz to get the Sonos speakers connected, then switch 5GHz back on afterwards.

I’m going to test later by temporarily disabling 5GHz so that my phone and all the Sonos speakers are definitely on 2.4GHz, then see whether all the rooms appear in Spotify Connect. 

Tested this now. I completely disabled 5GHz on the Plusnet router so my phone and Sonos were all on 2.4GHz, but unfortunately it made no difference.

Today Spotify Connect is showing only the Family Room Arc. Living Room (Beam Gen 2) and Kitchen (Sonos One) don't appear at all. Interestingly the Beam is actually one of my newer Sonos products, so it doesn't seem related to the age of the speakers.

All three rooms continue to appear and work perfectly in the Sonos app, including playing Spotify directly from Sonos. It's only Spotify Connect that isn't discovering them individually?

Thanks. I’ve done a bit more checking of the network connections for each Sonos room.
Family Room Arc – appears in Spotify Connect
2.4GHz, Channel 6, BSSID ending :29, SNR 63dB
Living Room Beam Gen 2 – does NOT appear
2.4GHz, Channel 6, same BSSID ending :29, SNR 70dB
Kitchen Sonos One – does NOT appear
5GHz, Channel 36, BSSID ending :28, SNR 35dB
So the Arc and Beam are connected to exactly the same WiFi access point, same 2.4GHz band and same channel. The Beam actually has the stronger signal, yet Spotify only discovers the Arc.
I’ve also tried completely disabling 5GHz on the router so everything was forced onto 2.4GHz, but that made no difference.
All rooms are visible and work normally in the Sonos app, including playing Spotify through the Sonos app. The problem seems specifically to be Spotify Connect not discovering the individual rooms.
Does this point towards a Spotify Connect/discovery issue rather than the WiFi connection itself? Is there anything else you would suggest checking?

Another interesting update. I have just tested Amazon Music as well as Spotify.

Amazon Music behaves exactly the same way – only the Family Room Arc appears as an available Sonos speaker. The Living Room Beam Gen 2 and Kitchen speaker do not appear.

All three rooms remain visible and fully controllable within the Sonos app.

So this doesn't appear to be specific to Spotify. It looks like the Arc is the only room being exposed to external music apps for some reason.

Given the Arc and Beam are connected to exactly the same WiFi access point, band, channel and BSSID, is there something within the Sonos system that could cause only one room to be advertised to external apps?

Some days odd things happen.

Something that seems to clear a lot of oddities is a system refresh, a bit of an aggravation to do but worth a try.

Power down ALL Sonos, reboot router and controller, power up the Sonos. With multiple APs, maybe reboot them along with the router?

thanks but i have tried all that before reaching out on here, even created a new Sonos account and reinstalled my system from scratch… stil no joy 😓

In the Spotify app, if you Clear Cache under Settings & Privacy > Data Saving & Offline, then fully remove and reinstall the Spotify app on your Android device, do the missing rooms appear as targets?

You could also try reauthorising Spotify in the Sonos app.

Also, do you have another mobile device that you can check on?
