7 grouped speakers Spotify issue

Tired to airplay an Apple podcast to the Salon pair and added also Salon Surround speaker pair.  The Salon Surround speakers will not play the podcast. Ran Diagnostic: 37761999. 
 

Clearly this is a Sotware/speaker issue. It is not related to Wi-Fi.  Sonos appears that they do not have a clue on what their products are they are doing.  Unless the Sonos answer is, “you need new generation speakers every few years?”   That, is not customer centricity.

Thanks for sending that diagnostic over @Mike_033 - I’m seeing some large fluctuations in interference, particularly around the wired Salon (R) speaker - are there any other electrical or wireless devices close to that speaker? If there are any other devices close to the wired Salon speaker, I’d recommend powering them off or moving them further from the speaker, the jumps in wireless noise are certainly enough to cause issues with playback.

I’d also recommend setting the SonosNet channel to 1, which looks to be the quietest channel from the most recent scan.

I’m also seeing a Quantenna Communications device acting as root bridge - is this a network switch, or some other device? Is the Boost connected directly to the router, or via said switch?

The only devices near the Play 5 R speaker are the modem, which the Play 5 is connected to, and the Sonos Boost. The Sonos boost is connected straight to the modem unsung the Sonos-provided white Ethernet cable.  There is a low voltage led light transformer that powers the lighting in a kitchen cabinet, and that is about 4 ft away, inside the cabinet. 

Understood - would it be possible to create some more distance between the Play:5 and the Modem & Boost, as well as changing the SonosNet channel to 1? After doing so, if you can test for at least 10 minutes and then send another diagnostic, I’ll be able to check if the levels of interference have dropped at all.

Do you have any wireless extenders or other network devices? The interference is the more likely cause, however I’d be interested to see what the Quantenna Communications device is, and whether that could be affecting communication across the system.

I will try, I suppose.   The entire Sonos value proposition is wireless, plug-and-play.  It is entirely contrary that these speakers can have so much interference.
