Problems with sound sync in latest Sonos Controller

20 replies
186 views

I am running the latest Sonos firmware 17.2.3 (build 90077070) with several Sonos One’s and a Sonos Move. My controller(s) Macbook Pro M5 Max (MacOS Tahoe) and iPhone 17 Pro (iOS 26.5) -- iOS Sonos is also up to date.

After a recent update to Sonos, I have again experienced speaker sound sync issues. I have not changed anything in my setup or configuration. I have one Sonos One hard-wired that was intended to overcome prior similar issues. These speakers are all within less than 25 ft proximity to my Netgear Orbi RBR850.

So my question is has anyone noticed this degradation since recent Sonos controller updates? I recall this being a long-term Sonos issue.

Haven’t noticed this as an issue across my many grouped rooms, or individual speakers. It sure sounds like potential wifi interference , possibly from outside your home / network. Usually, the first device in the list of ‘grouped’ speakers is the coordinator, and handles the sync for all other speakers. Have you tried starting with the wired speaker first? It could make a difference, or it could not, but worth the test.

Honestly, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here.

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.

I'm not sure your split networking is your best option. Having your Moves on Wi-Fi and your Ones on Ethernet/Sonosnet might be complicating things. Removing the Ethernet and having all on Wi-Fi might be a better choice.

Try removing the Ethernet and check the signal levels on the Ones, if they are adequate you should be able to stay all Wi-Fi. If there are still issues the previous post is good advice.

You might also want to check for firmware updates. Firmware 17.2.3 (build 90077070) isn’t even close to the current version.

Looking at one of my S2 Sonos Ones, it is running firmware 18.4 (build 95.0-77060)…

Yes, that would be the current version. I think the OP is pre May 2024, unless it’s a typo. I didn’t think a current controller would allow that kind of mismatch.

Edit: Or not, I don’t know. I don’t see build 90077070 in the release notes. And it’s been 18x for a while.

Could it be S1? I don’t have an S1 system to compare against. And lord knows I’m not smart enough to look at the download packages ;)

A Playbar is in the profile so S1 could be a possibility if the Moves are 1s.

Probably worth considering a swap to the S2 system if it is on S1 now.

Current S1 is Version 11.16.1 (build 572374170).

Frankly, I don’t trust the release notes. I ‘know’ that Sonos doesn’t keep that data ‘up to date’ all the time, for their own reasons. I trust what is running on my system, after double checking for updates that I may (unlikely) have missed.

Don’t get me started on why Sonos doesn’t keep that reference data up to date. I think I’ve been fighting that since I first started using Sonos. It’s mildly frustration to OCD data folks like me.

I looked but failed to find any S1 release notes or version info. Even tried the search AI assistant.
