rear surround keep cutting (ARC SL, Mini Sub, two Sonos One)

recently purchased an Arc and replaced my beam. Everything states the same by using physical Ethernet to connect all devices. However, after I set up the surround sound, I noticed those rear Sonos ones behind me getting cutting sound. Here is my diagnosis code: [redacted]

 

Moderator Edit: Recorded and removed diagnostic number

Yes, all Sonos devices using same network switch. I also disabled the WiFi on every devices

 

There’s your problem (in bold).  Although it sounds counterintuitive, a wired connection requires more hops than the private, dedicated, one-way, direct wireless connection Sonos uses for Sub/surrounds.  That’s why you are getting breakups in the sound.

You’ll want to ‘edit’ your post to delete the diagnostic number. We in the public don’t have access to them, and Sonos seems to delete them as a moderator action when they run across the posts. 
 

Since you’ve posted on the Sonos community, rather than calling Sonos Support, can you explain your ‘getting cutting sound’ reference?

You have Ethernet run to the Arc, Sub and both Ones?

Do the Ethernet cables all run to one switch or are there multiple hops between them?

Have you disabled the internal Sonos radio, the default connection for Sub and surrounds?

Have you powered down all your Sonos, rebooted the router and powered up the Sonos.

Still sad that after all the requests to rename that switch something accurate, or at least less misleading, it is still causing folks that see it and don't understand what it does grief.

Not to mention a warning when you click it off on a soundbar/Amp connected to surrounds and/or Sub.
