problem setting up

I recently bought an Ultra + 2xEra 300 for my new home, I wall mounted the 300’s couple of weeks ago and added them to the Sonos app.. and played a bit of music through them waiting for the day (today) that I’d set up my TV and start up my Ultra.. I followed the start up instructions for the Ultra via the app WiFi connection TV connected via the HDMI arc then added it to my Living Room to join my 300’s. Turned on my TV sound coming from the Ultra but nothing from the 300’s even when I tick the yellow box for 300’s in the set up menu… Could someone be kind enough to let me know what I’m doing wrong.. sorry I’m new to the Sonos family Kind regards Anthony

If the Era 300s are currently set up as a stereo pair, you need to separate them as a stereo pair first:

Then under the Arc Ultra’s settings, select Set up Surrounds to add them as surrounds to the Arc Ultra:

I don’t know what you mean when you say you “thought the introduction of the Ultra would automatically configure into a surround layout” but it’s not quite that simple.

  1. As long as the 300’s are set as individual rooms all you need do is go to the room with the Arc Ultra and select “setup surrounds”.
  2. The app will see the 300’s and ask per speaker if you want to use the selected 300 as a surround.
  3. Of course you select the “yes”option.
  4. After the selections are made the app will play a tone through one of the 300’s while you face your TV and select the correct 300 (playing the tone) as either the left or right.
  5. From than point the app/Arc Ultra finishes the surround setup.
  6. The app even displays a graphic of the Arc Ultra and 300’s positioned as surrounds as a visual representation for ease of setup. 

Question: Did you not follow the procedure I just referenced 🤔

Same problem with 2 Era300 to pair with Beam 2 gen soundbar. The problem is that the app dont recognize any of the Era to be available so no prompt is launched. I had two sonos one set as surrounds before, so I did it once 3 years ago. No clue how to resolve this problem now.

Did you remove the Ones as surrounds in the Sonos app?
