Pretty frequently, my two paired Play 3’s will drop the stereo pairing and just both play one channel (either both left or both right), and I have to re-add the stereo pair. This only happens when playing through my Connect.
This happens at least twice a month, but I’ve never actually been sitting in the room listening when it goes down, so I tried to capture a Diagnostic ticket in the moment.
Diagnostic 1730205163
After capturing the ticket, I separated the pair and tried to re-add. Sonos couldn’t “find” the Left speaker - which is the one plugged into the router.
Then, all of my speakers disappeared. Luckily, this happens frequently enough that I know all I have to do is go, room by room, and unplug all my speakers, recycle my router, and then go room by room and plug them all back in. Easy peasy!
Before anyone can say “interference”, I’ll say it again: the Connect and the router are in the same room, less than 12 feet between them, direct line of sight. The router is a TP-Link Archer A9 - which should have enough power to get that first down.
