I know this topic has been beaten to death, but in my digging I haven’t seen a scenario that seems to quite line up with this one.  Hoping it’s an easy fix.

I have a bunch of Play:1’s and a a playbar littered around my house.   I have one single speaker in a kid’s room that I find goes ‘unavailable’ for a couple of minutes multiple times per hour.   (I note this in the log of my Home Assistant environment that Sonos is integrated into).  Actually playing things on the speaker works just fine.  The Sonos app works just fine.  But according to that log, the flipflopping to unavailable keeps happening.

I don’t believe it’s an HA thing (beyond it maybe possibly timing out a bit faster than it should perhaps), because it is ONLY happening on this one speaker for the entire house.

I recently switched from SonosNet to wifi-only in an attempt to combat this, but no avail.  When I was on SonosNet the speaker did show it wasn’t getting a great connection.  However since unplugging all the wires and moving to wifi only (I have a very stable wifi environment for the most part), every single speaker on the matrix shows green with the exception of the PlayBar in my basement, but that playbar has no connection issues.  Certainly the one speaker I’m having trouble with has been solid green since moving it to wifi.

They’re all on the same subnet, no vlans or such to mess with.   Any suggestions on what to look at?
