Hello all! I thought I was fairly tech savvy after working in the tech industry for 22 years. However, I’m having one heck of a time getting my Sonos arc SL and two era 100 surround speakers to speak together to create a home theater environment. 
 

I have the Eras paired as a stereo pair in a system called ‘Living Room’

my Arc SL is in a different Living Room system that is Living Room Arc SL

 

error message:

Two compatible Sonos speakers are required to add surrounds. Make sure your products are powered on and joined to the wireless network (which they are)

Huh, seems odd. I’d be tempted to first split the Era 100s into a not stereo pair, placing them in two ‘rooms’ in the Sonos system, then check for updates, or factory reset them. It sounds like the controller thinks they’re two different types of speakers. 

Once they’re set up in two separate ‘rooms’ in the Sonos system, you should (normally) be able to add them as surrounds to the Arc SL. However, if there is still a similar error showing up, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. 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.


Thank uo

Worked like a champ!  Thanks so much for your help!
