Audio Cutout - but only when sourcing from playbase or playbar

I have a playbar on one tv and a playbase on another tv, also several other play:1 play:3 and connect:Amp.
When I use my phone or laptop as a source and switch to 'party mode', everything is perfect - always.
When I watch either TV with only it's playbase or playbar - it works flawlessly.
If, however, I attempt to group any other speakers to either the playbase or playbar sourced by TV sound - the audio cuts out every few seconds. This just started fairly recently - I recall watching some football this way (party mode) with no issues the entire evening - but by the time playoffs rolled around - it's not usable in that way. I'm unable to think of any significant changes that have been made since I recall this working - maybe the playbase is that new - it arrived on christmas day. :)

Another interesting thing to note is that the source playbase or playbar (depending on which tv I want to broadcast) never cuts out - only the satellite grouped speakers cut out - and they all cut out together.

This occurs with 'smart app' sourced audio as well as DTV sourced audio - I'm quite confident it's not a tv/receiver audio output issue in that the two setups are completely different but are behaving identically - also - the 'main' speaker never cuts out.

I tried switching between BOOST and home wifi - no change.
Only a single play:1 is not hardwired to the Gigabit Cat6e LAN.
I tried disabling the wificontrol - no change.
External interference is unlikely - I don't have many neighbors nearby.

I ran the diagnostics: 8505842
Currently playing Netflix Smart TV App in Master Bedroom - grouped in party mode and cutting out everywhere but MasterBedroom Playbar.

Noooooooooo!

Here's my new diagnostic, cut outs are back...that didn't take long after posting the contrary.

This was a great explanation of STP - stick with it and it all comes together.

One of the points it made was that I should get all of my SONOS devices on the same switch...I'm not sure my plans can accommodate that requirement. I'll move the connect:AMP to the switch in the other closet and see if my issues resolve.

The next Q would be how to make that not necessary...as I intend to have a stack of connect:Amp in the A/V media closet - but everything else is connected in the main networking closet on the other side of the house 😞.

I seem to have stumbled onto a change - which may explain why I thought it was working for a while.
It's only the single wireless Sonos:One that is skipping now (all other devices are hard wired) and I think are OK.
When I ping any of the wired units, my time averages under .300 ms.
However when I ping the lone wireless IP, I think it shows latency during the cut-outs.

Here's a snippet from a ping to the wireless unit:

Defect appears to be isolated now to the single speaker which is not hardwired.
I was able to follow the Sonos guide to configure STP on my managed switch.
Was kind of a pain tracing all of the Sonos connected wires to the exact ports but finally got it sorted.
The lone wireless Sonos is the only one experiencing the cutout - it's identified port is the same as the Playbase:Living which I think tells me that it's not actually using my WAP, which is on a different switch - but instead is being tunneled across Sonos:Net and through the Playbase hardwire connection.
If that's true, then I've successfully isolated all of the Sonos devices to the managed switch and configured STP for those ports and restarted the switch.

I switched the connect:AMP back to the unmanaged switch to see what would happen.
No change, only the wireless Sonos:1 experiences cut-out.

I think I'll move that Sonos somewhere and get it wired, adjust it's port setting and see what happens...

No cut outs when wired...

Here is a diagnostic with everything wired: 753391532

Here is a diagnostic with the Play:1:Kitchen (R) wireless: 1656533661

Any help is appreciated with the analysis.

I think we've got it! My wifi was on channel 6 and my Sonos was on channel 6, also one of my neighbors is on channel 6 - and I think he's got some Sonos...
I left my Sonos on channel 6 and moved my WIFI to channel 11.
I think I'm good - been listening for a while and all is good.
We'll see if it holds for some college basketball watching...

And just to double check...the ping times to the wireless unit are much improved and consistently under 2ms!
