Not enough information to be certain, unfortunately, but I’d start with a simple network to fresh, by rebooting your router, followed by a reboot of your speakers. If that doesn’t resolve the issue, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

Same problem here. Spotify will stop playing randomly. I'm guessing spotify and Sonos network problem. 

I am having the same problem, however let me detail my observations:

I have several Sonos products, but only my Sonos PLAY:5 has this specific problem - and only when playing Spotify.

How can I be sure?  

• Playing spotify only on PLAY:5 the problem persists
• Grouping Connect:Amp and PLAY:5 - Connect.Amp keeps playing, while PLAY:5 randomly pauses. When pausing, PLAY:5 looks correct, that is indicator light is white and not blinking
• Playing on Sonos One and PLAY:3 no problem
• Playing other streaming music services - no problems
• In my summerhouse, which is very small, but has a fiber connection from another service provider running on different gear, - my summerhouse PLAY:5 being the only device besides my iPhone on the WiFi, STILL have a problem playing Spotify and still no problem when playing other services.

Being an old (or kind of old) network specialist, I think I have analyzed all kinds of aspects of the network connection, switching, bridging and routing issues etc. and I strongly suggest that either Spotify has a streaming problem or a caching problem, or - and this is way I write in this community - the PLAY:5 in combination with Spotify has some kind of an issue.

Please consider if the playing devices with issues, share a commonality 

Hope to hear from you all.

I’m having the same problem, but it’s not random: Spotify plays fine until it comes time for the ads (non-premium Spotify), then the audio stops.  The app indicates that the ad is playing, but there’s no sound.  It will sit like that indefinitely.  If I press “pause” in the controller, then “play” again, the ads will start playing and when they’re done, playback will resume as normal.  It kind of seems like it’s a Spotify problem more than a Sonos problem.

Have you contacted Spotify? 

I’d agree with your assessment, by the way. Sonos only is aware of the instruction to play the stream from the server, it has no concept of whether that source is a song or a commercial. There must be something on Spotify’s server….as a guess, the commercials are in a format…no, they wouldn’t play when you reconnected. I’m baffled. There must be some discontinuity on the Spotify server. 

I have seen the same issue with Spotify pop up over the last couple months… in my case it happens on more than one device.  Spotify gets “stuck” at the beginning of an ad. I understand that this is likely not a Sonos issue as the stream is coming from Spotify… but it seems like someone from Sonos should test and get with Spotify since I believe this is affecting more than a few people.
