Hi @Stewart_9, thanks for the update and for sending a diagnostic report of your Sonos system. Upon checking, You’re right it detects that the Sonos Amp is hardwired and the wireless capability is turned off. but the system can’t detect any issues on it. Have you tried it on WiFi if it will be the same issue? Is it happening on all kinds of sources when playing on the Sonos Amp? Are there any changes made before this issue occurred?

Keep us posted on how it goes and we're here to answer any further questions you have.

I had the same thing with unwired … (WiFi) diagnostic. 547738929.  I will try different sources but have tried that before.  This started occurring when I upgraded my other amps in my system.  This is the only one I have left but this one is deamed modern so I did not upgrade (and did not want the unnecessary cost to do so)
