Hi, I ‘ve setup the Arc Ultra, Sub 4 in Media room, and Era 100 two speakers in living room. I’m unable to setup surrounds as Era 100 speakers. Can you please check and suggest.

Thanks

We can’t ‘check’, we aren’t Sonos Support employees. This is a forum, unfortunately not where Support works. 

If I were to guess, you need to put your Era 100s in two separate Sonos ‘ rooms’ , then use the controller to add them as surround speakers to your Arc Ultra.

@Airgetlam is correct. To be clear you don’t need to physically move them to different rooms. 😂

Just set them up with different names (which is a room in Sonos speak). Then go to the room with the Arc Ultra in the app and select “add surrounds”.

Happy Holidays!
