Only one speaker plays at a time.

I was gifted a Sonos Era 100 on my birthday. I already owned a Sonos One SL. I was already disappointed to find out that I could not pair them together, and could therefore not use them as TV speakers. I understand the reasoning for this, but it’s still annoying.

Now I’m having this problem where I can’t even get them to play music at the same time. In the Sonos app I select them both to play at the same time and it says: ‘Era 100 + 1’ or One SL + 1’ but the ‘+1’ speaker never actually plays anything. Everything in the app indicates that both speakers are playing (the little sound waves beside them are both moving) but sound only comes out of one of them. Both speakers are fully capable of playing independently and if I change which one is the ‘+1’ I can change which plays music.

I have been able to fix all this temporarily by plugging out both speakers and plugging them in again, but they soon revert to this problematic state.

Does anybody know why this is happening? I’m getting pretty annoyed at this point.

Hard to tell, but as a guess, one of them isn’t updated yet, for whatever reason. I’d check in the controller for updates and apply them, then try to group them, and play something. 
 

If that doesn’t work, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. But don’t post the resulting diagnostic number here, they get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
