📲 New Sonos App & Player updates for early-March are now available! 🔊

Hi, 

Thought I'd share  my first update issue with latest app/firmware, normally the updates are seamless, however the latest update, my system lost all the speakers era300's and sub-mini , they wouldn't bond with the soundbar, tried the usual steps, without success so factory reset  them, still with the same result, my network could see them, yet refused to bond.

I even changed the network on all devices same result.

Eventually spoke to support, who were pretty good, it was found UNP was switched off in the controller app; soon as UNP was switched back on, the speakers were immediately available to the app for configuration. 

I guess with UNP set to off in my app  caused  issues; so why only now has this surfaced, and the other updates firmware, didn't mind UNP off?

Its not end of days stuff, I'm happy the system is back, just curious.

I'm not a fan of unp, I think I switched it off last November/December 2025 when I bought the system, however this was the first time having unp set to off in the app upset system updates,

​@Dg7559, What is UNP? UPNP?

I thought UPnP was so other control point apps could see the Sonos devices and play to them using UPnP/DLNA.  I use that capability a lot so that I can play music that is not indexed.  I access the two MinimServer servers.

Reporting all devices connected via ETHERNET cable no longer work after this update. Devices with WIFI working without issue. If unplugging the ETHERNET cable, device will connect with WIFI right away. This update has caused ETHERNET connected devices to stop working. System contains three devices, two on ethernet, one on wifi. Only solution at this time is to remove ethernet cables from devices. Level two support call scheduled.

 My Port on Ethernet works…. I think.  All unplugged now with storm coming in.  Will check again after storm.

 The Port WiFi was also turned OFF.

Yes,  my bad

​@Dg7559, Thanks a lot for sharing the solution.

What happens if you disable UPnP now the speakers have been reconfigured?

My understanding is UPnP is only required for legacy Sonos Windows/MacOS Apps, and also 3rd Party integration. I have HA integration, so require UPnP, but when I disable UPnP, iOS App still works fine with latest Sonos system firmware.

I switched UPNP off in the app, when I bought the system late last year, all previous the updates all went through seamlessly.

However, this March update, caused the system to lose the speakers, i could see them on the network, Sonos confirmed from their end they can see them on diagnostics.

After Sonos mentioned to turn UPNP on, instantly the speakers were presented to the system for configuration. 

I saw other instances of this condition on other forums. 

I'm just happy all is working, On router level UPnP is disabled, so I assume the private network, was affected with this update, requiring UPnP on for the controller app maybe; who knows?

 Plugged the Ethernet connected Port back in ( we had a storm ).  It shows in the app.  My system, though, has always had UPnP on.  I believe it is on by default.
