Hi, 

I just recently swapped out my old playbase for an Arc.  I had 2 Sonos Ones and One Subwoofer on the old system.  The Sonos Ones were Alexa enabled.  When I changed out the Arc and readded the Sonos Ones to the new arc (I did a factory reset on the speakers before doing this), the mics on the speakers will not turn on or add the Alexa function.  The Arc has it so the room is fine.  Can a surround system only have one component with Alexa functioning or is there a bug in my system?  I have tried to reinstall and then add the S1s twice but same result.  All the components do show up in my Sonos app.  I don’t know if this is related, but when adding the S1s back to the app, it used “Sonos” and not my wifi.  

Sorry for the long post, but wanted to be as complete as I could.

Thanks,

Jim
