Commercial Setup Sonos Port Static Distortion

Sounds more like some sort of internet distortion, rather than anything with the speakers themselves. There is no way to schedule a reboot, but the next time it happens, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

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.

What are you power cycling? PORT? JBL?  Both? Is this a stereo system or mono? If this is a mono speaker system, how are you combining the left and right from PORT?

Power cycling the port.  Power cycling JBL does nothing.  JBL takes stereo input and converts to mono internally.  

I don’t recall any previous reports of a similar issue, but Mother Nature is never fair.

I’m thinking that there is a hardware issue (somewhere). Hopefully, something will show in the PORT diagnostics. As a backup test try temporarily replacing PORT with another source. This could be anything that’s on hand, such as a phone/pad, CD player, cable box feed, etc.

Thanks, it’s hard to replicate so I am going to replace the port tomorrow with one I have on the shelf to see if I get a change.  I’ll update here after some run time.
