What speakers are dropping out? My suspicion is wifi interference , but there are other, more remote possibilities.
I would certainly 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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
To answer your question, the complete TV group drops out, for only 10 sec or so. All other speakers in the house continue to play. The Playbase is directly wired to my router.
I’ll take your advice with contacting Sonos Support.
