Exactly the same problem with Sonos amps, Sonos Move, Sonos One with Spotify connect on a freshly rebooted system. Do it every time. Frustrating.

Don’t happen with playlist, only when launching single hits.

My Move and Spotify (via Connect or Sonos App) work perfectly on S1.

I believe some people have had problems with the Move on S2?.

Sure sounds like wifi interference. Have you submitted a diagnostic and called Sonos? That technical support team mentioned in the post before yours would likely be able to help. 

Just came here from Google.. having same issue. Playing via spotify app and connecting to move, plays in middle of song showing progress bar a few seconds in. Using Android. Move is fully updated. Seems to have only recently started for me. 

Hi @acmove @wefef @ryanbv @tiaskillen & @danielrosenq 

Please ensure both your Sonos systems and your Spotify apps are fully up-to-date. Reboot your speaker, your device running the Spotify app, and your router. If the issue persists after these steps, I recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

I’m only using Spotify ‘Free’ here, but not seeing the issue with the ‘Connect’ feature, nor with Airplay. Maybe if anyone uses Airplay, it might be worth trying that, just to see if the same thing happens, in which case it could just be a local wireless connection issue, which might be solved (hopefully) simply, either by switching WiFi bands in some cases, or a change of router/SonosNet channel (perhaps)?

I read in other threads here too, that signing out of Spotify ‘everywhere’ via the users online account and removing/reinstalling both the native Spotify App and the Spotify Service in the Sonos App can often assist with such issues too, so perhaps consider giving that a try (if not tried already).

Same thing for me. I have an iPhone 12 Pro and 2018 MBP i7. Whenever I stream from the Spotify app using the “select a device” feature to any of my Sonos speakers, it’ll start blasting from the middle of the song. This has been happening for 2 years. In terms of internet, our ISP is Xfinity. We have fairly decent wi-fi speeds on account of our mesh TP Deco router. We get about 500Mbps down near the main router and no less than 50Mbps at our furthest part of the house.
