Connect (GEN 2) suddenly out of sync

I‘ve had exactly the same issue with my Connect since the 14.18 update - 

Unplugged router...unplugged every Sonos device and all 4 B&O towers...waited almost an hour...plugged router in first...waited almost 15 minutes for everything to settle...then started with the Sonos Boost (hardwired to the router), and slowly but methodically plugged all Sonos devices and B&O speakers back in and…

Voila! it worked! But…

After about 10 minutes the echoing began again, and the sole culprit were the speakers connected to both Connect’s (GEN2).

Now I see another user (DunkirkPie) has the same issue since the last update, so at least it’s not only my system, but alas, the issue still exists ☹️ Thanks, John B for being patient and trying to help.

Guess I’ll just have to wait for another update. Either that or break down and purchase a couple of “Ports” (just kidding...)

Yes it certainly looks like you are not alone. It may (or may not) be the case that other conditions need to apply for the sync to be lost.

Did you form your group by starting from a Connect or another device, or did you try both?

For years I’ve only had one group called MAIN, and it connects (no pun intended) the Playbar under the TV, the Play:1 in the kitchen and the two B&O towers through the Connect (GEN2). The grouping always begins with the Playbar, which is ARC connected to the TV. So...I just tried grouping with the Connect first, which didn’t work because turning on the TV immediately connected with the Playbar, so I forced the Connect to connect to the TV as a source, even though the TV was off, and quickly added the Playbar and the Play:1. Again, it worked, with perfect syncing, but only for a few minutes, after which the B&O’s began lagging behind the Playbar and the Play:1.

Good suggestion (I wouldn’t have thought of it), but to no avail.

I have this issue too!!!!  I’ve been on the phone with Sonos customer support twice today and their “answer” is that it’s because my Connect is on a different network than the rest of my system.  I have a Netgear Orbi Mesh system so the speakers are going to be on different home satellites.  Was not an issue for years until a few days ago.  They’re pleading ignorance on it being their problem.

Hi @BigMCA 

Sorry to hear that. It can be quite difficult for agents to be aware of certain issues if they don’t search for the right phrase - especially if they are particularly uncommon issues.

I can only ask you to please get back in touch with our technical support team and ask the agent you speak to to search their documentation for “clock pull”. I can’t guarantee that they’ll find that particular issue in your diagnostics (I haven’t seen them), but if they do, they’ll then know what to do with it.

I hope this helps.

FYI I was having this issue and it has now been resolved:

I’m now on call #5 with this issue.  It seems they’re almost at the point to replace it, but of course want to try just one more test.  It’s pretty damn infuriating.

I’m having the exact same issue! A Connect (S2) is initially in sync with the rest of the Sonos network and then falls out of sync over time. The audio source has always been the Sonos app (not line in) and the audio system connected to the Connect is old-school analog, no DSP in it. It’s been working for years and now is frustratingly unstable. I’ve been on chats and calls with support many times. I’ve spent a Saturday running an Ethernet cable through the house so I could hardwire the connection from the router to the Connect as well as a Sonos Five that has always been directly wired to the router (now both the Connect and the Five are wired).  It still falls out of sync. Cycling power to everything in the network will fix the problem, for a while, and then the Connect will fall out of sync again. I’ll get on the phone with support again on Monday but is there any way I can point them to this thread?
