S5 speakers - volume keeps dropping whilst orange light flashes.

My S1 set up includes 3 x S5 speakers. 2 are set up as a stereo pair and the 3rd as single room speaker. Over the past few weeks these speakers have started continually dropping their volume when the system is first used in the morning. Increasing the volume works, either by using the app or the volume buttons on the speakers, and corrects the volume for a short while and then it drops again. At the same time the lights briefly flash orange before returning to static white once the volume has dropped.  After an hour or so of use this settles down and the volume remains stable for the rest of the day. The other speakers in the system are not affected, several x  Play 1 and a Beam. I have tried unplugging them for a short while before plugging them back in and several times unplugged all the speakers and router but this hasn’t improved the issue. 

I also have a Roam which operates separately using the new App.

All system updates have been made. Curious why this should have suddenly started to happen and wonder if it is fixable? Any ideas please?

Not sure this can be easily explained. The light (LED) flashing sounds like a network issue, but it’s hard to be certain. And that wouldn’t, I think, explain changes in volume levels. 

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks Bruce, I was thinking of contacting support but before doing so wanted to check to see if this was a known issue with a simple solution.
