Do you mind answering a couple questions about your system and network?
With 15 speakers, do you have any of them hardwired to your network? I ask this because you have speakers that can take advantage of Sonosnet, which may make your connections more stable.
Have you seen this post on how to resolve some Sonos issues? This may also help with your issues:
I sometimes feel like a broken record saying this, but I have 11 speakers in my home. 6 of them are hardwired with the rest connected directly to my soundbar or Sonosnet. I do not have any connection issues, and only some very minor issues that are not worth mentioning.
I also do feel that there is a true competitor for Sonos right now
I haven't found anything better. Worse I've found, short support lifetimes I've found.
Sonos is well on the way to being a standard case study, maybe replacing Crown Cap and Seal? The original decision was bad, the decision not to offer a rollback is questionable, the progress on getting back to where we were, poor. Customer communication is laughable, it appears they even perfer Reddit to their own forums for that.
Still this is nothing new for Sonos, they have messed up before and come back, this just another screwup, a SuperSized one, that is going to cause them long term problems, but not new.
As with past messes I'm sitting it out and living with what we have. I even bought some new Sonos over the holidays. Also giving thanks I don't work in their programming shop!
My experience is that it makes absolute sense to separate acoustic and streaming components in the event of defects or when the manufacturer starts to go crazy... Since I have equipped my home network with UniFi anyway, I have purchased the Unifi Power Amp for the office and living room. It's certainly not a solution for the kitchen, bathroom and other rooms, but it's a start, with the hope that something else will come from UniFi in the future. With Sonos, I have no idea how they could convince me again...
