Can you confirm what music sources you have defined in the Sonos App?

Red wine always help, particularly when dealing with the Sonos App! Online radio stations ie Mi-Soul, Spotify, Apple Music my playlist on my Pc

Maybe sign out/in your Sonos account within the App and try reauthorising the Music Services that are not working for you and see if that perhaps fixes the issue. Also ensure your mobile controller device and speakers are using the same WiFi access point, if you have any WiFi extenders, or repeaters etc. 

thanks Ken - I will give it a try and see how i get on and hopefully let you know - maybe after a Bottle of Red!!!

Same issue for me…. Can’t seem to fix it!

its ridiculous really it is - i ended up on the chat, they helped somewhat however, I still have difficulties playing what I want and when

Then skip the chat, and call Sonos Support directly to discuss it.

What are the ‘other’ audio source/tracks that you’re having difficulty with when trying to play them in the Sonos App. Are they perhaps out-dated shortcuts held in your Favorites, or perhaps links pinned to your Home Screen?

Hi ​@Fizzelle and ​@amitc 

Welcome to the Sonos Community!

Sorry to hear of this issue you are having with the error message displaying when trying to play from Spotify.

We’d like to investigate the situation further.

Could you please recreate this issue, taking a screenshot of the error message and submitting a support diagnostic afterwards? Thanks. Please post the screenshot here, and just let me know that you have submitted diagnositcs (without posting the number here) and I will pass them on to an engineer. Thank you.

Thanks all. I ended up calling customer support and they seem to have rectified the problem for now.

Same for me. Randomly with trying to control the volume on apple TV. My network is fine, it's the Sonos buggy system. Sonos, you suck. 

I too called Sonos support and sat in the wait queue for 35 min. They told me that a wifi extender is not supported and to get a mesh wifi system. In the meantime, rebooting the router temp solved the issue. 

If rebooting the router helps your system please see my article: 

Je comprends tout à fait votre frustration, surtout compte tenu du prix des Eros 300. Le message "no content" peut être lié à un problème de configuration ou de compatibilité dans l'application. Je vous recommande de vérifier que tous vos appareils sont bien connectés au même réseau Wi-Fi, et que le firmware de vos enceintes ainsi que l’application Sonos sont à jour. Si le problème persiste, un redémarrage complet des enceintes et du routeur peut parfois régler ce genre de souci.
