For about the last month, my Sonos Playbar and a pair of Play 1 speakers temporarily stop playing together after grouping.
The Playbar is also used as a TV speaker, which causes it to ungroup from Play 1 speakers when the TV is on. That’s the way we prefer it for TV watching.
When listening to music, we prefer a whole room effect, so we group them together.
For about the last month, especially when listening to SiriusXM, the grouping works great for about the first 10 minutes, then the Playbar drops off for about 3 minutes, so only the Play 1s are working. Then the Playbar returns to the group by itself, although the overall sound quality is degraded.
I have tried powering down all components, then rebooting, to no avail.
I live in a high rise building amidst many other WiFi systems. The components all work off a Wifi extender on a Google Fiber network. All the components are 12 feet or closer to the extender.
Grateful for any help. I have submitted diagnostics Confirmation #515872033.
