Lost surround and sub ( after update ?)

This.

If Sonos works over 5ghz there’s zero reason it shouldn’t work as well over ethernet. Unless your ethernet network is broken any switched Sonos setup on ethernet will have sub ms latency and effectively no jitter. This environment should be perfect for syncing surround. 5ghz is always going to add latency and connection jitter, even if it’s minimal.

I suspect this being “not recommended” is more a byproduct of the fact that, most of the time, simply plugging in an ethernet connection to a Sonos speaker will in fact cause more problems than it solves. If you aren’t using a VLAN to isolate your speakers or correctly (or configuring your STP values, or disabling wireless outright) you can end up with odd network pathing (switches choosing Sonos wireless links over 10G Ethernet ports, for example). 

Sonos -really- should have fixed their STP implementation with S2.

Also moved away from SSDP to mDNS like everyone else does. Also cleaned up the player / controller TCP/UDP port insanity. Also…

Having the same issue since upgrading to 14.6.  Occasionally when I start watching content from my apple TV, I’ll notice that my sub, play 3 surrounds or both no longer work despite seeing them connected in the app.  

Only fix is to put my TV and apple TV to sleep, then unplug my arc.  After I plug it back it, I turn on my AppleTV, which turns on my TV and then everything works.  

Well, its Tuesday @Nylon - let us know if you hear anything!

Update May10: After the issue going and coming back, I checked in with Sonos as wanted to try phone support rathar than chat. They ended up saying there was actually a hardware fault with my right surround and arranged a warranty exchange, and said that was that. Sadly, when switching in a 'working' surround the issue came back straight away again so another call led to them retracting that solution. Further digging meant they then saw there was an internal case number for this, and it was a software issue. They said to just hang fire and let the developers work on it and wait maybe call back in 2 weeks to see if there has been a software update and disable the surrounds in the mean time. **IMPORTANT: This is NOT anything to do with version '14.6' which is the app software version, this is actually to do with the speaker software which is on version '68.2'**... sadly not sure there is anyway for us to check this has updated though. I would advise people to either wait, or if they havn't done so already, speak to support on the phone and give them various diagnosis numbers for the issue so they have as much information to hand and can see people are having the issue.

The two are equivalent. Build number prefix 68.2 equates to external version 14.6. Controller apps and players need to stay in step.

In Settings/App Preferences you’ll see both version and build listed under “App Version”.

Likewise in Settings/System/About My System each device lists its firmware version, with the build number in brackets thereafter.

Anyone else's heart sinking at the prospects of waiting another 2 weeks to get full surround sound back? 😥

@ratty Thanks for clarifying, the support agent said otherwise so that’s good to know!

Will do if/when I do.

I have the exact same problems as everyone on this thread. Started after last update.

After a reboot, I can easily trigger the problem by playing spatial audio in Apple Music and pausing.

Often it also occurs when pausing and resuming playback on the Apple TV. 
 

Diagnostic number 1873195472

For the record, I should add that I have my Apple TV set to Dolby Digital and have tried Dolby Digital Plus as well. Since I don’t have an Atmos capable TV (Sony, one generation too early) I don’t think I have any Atmos-related settings anywhere.

But even so, I get the problem frequently. So it appears multifaceted and not always tied down to Atmos etc. It seems to affect many people with different setups and the common denominator being shifts in playback format (since it occurs when pausing or switching playback sources within the Apple TV).
