Probably best if you were to submit a system diagnostic , and call Sonos Support to discuss it. But for potential hardware failures, it’s possible nothing would show up in that diagnostic….but still a better place to discuss it. This community can’t really help with that issue.
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 phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
