SUB gets out of sync after update to 14.6 - bass is delayed making it sound like reverb


Userlevel 2

After upgrading to release 14.6, I’ve noticed that the SUB frequently gets out of sync (lags) relative to the ARC.  When this happens the SUB can sound like reverb - it really degrades the sound experience quite a bit.  Removing the SUB and then adding it back in does not seem to remedy the problem -- the only thing I have found that clears this state is power cycling the ARC.

Same issue here

arc, sub gen 3 and 2 Sonos play 1’s for surround. 

I feel like I'm having this issue as well.

My set up is beam (connected via gigabit eth), 2x one sl's (no eth) and a gen 3 sub (no eth).

Before buying the sub today, I've noticed no lag between the beam and the ones but after connecting the gen3, there is noticeable lag from the sub.

I tried disconnecting the eth from the beam but that didn't seem to make any difference. Lag is present listening to Spotify service within Sonos app, streaming directly from Spotify and using the Spotify app from within the tv. I haven't noticed lag when using non-music sources but I think it's harder to notice it compared to a constant beat of a song. 

Pretty pissed off though. This gear ain't cheap!

What response did you get when you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it?

Same issue here. I have to remove the sub from my setup and add it to correct the problem, but it gets out of sync again a few days later. Hope this gets fixed soon as it is rather frustrating to have paid this much money for a system that doesn’t work properly. 

Issue just occurred again!  This time I removed and re-added the sub to fix the issue!  Come on Sonos,  this is crazy, get it fixed.

Just spent 3 hours messing around with my setup before finding this thread ..

Its so bad.  I own more than 20 Sonos products in 2 different homes and this has ruined my experience with the fancy new Arc.

All my Gen 1 and 2 stuff still works great..  S1 for life.😆

 

FWIW rebooting the Arc fixes my issue temporarily as well.  

I actually bought an S1 only unit just so ours always fails the "Upgrade to S2" test, £50 well spent on a ZP90!.

Time and time again forced updates ruin what is a good system.

appreciate the reply…yep, they are set up as surrounds.  there are 2 options to control them, tv or music.  doesn’t matter if i stream pandora from the tv app or my phone, same echo effect.  this wasn’t an issue until a month or two ago, so that points to a fw upgrade from sonos.  as i said, same setup at a different house except using a beam and no issues.  others seem to be having the same issue.

Are you sure you have the surrounds configured as surrounds?  Correctly configured, the surrounds should not be playing the same signal as the fronts, so an echo would be impossible.  The only way for them to play the same signal is if you had them grouped, and a grouped speaker playing a TV source will indeed have an echo. 

so unhappy with my $2k system...arc, 2 oneSL surrounds and sub.  The surrounds and sub get out of sync with the arc creating a nausiating echo effect.  have the same setup at another house except for a beam and it sounds great.  Seriously Sonos, fix this issue, you're loosing major credibility.

I have been expecting the same problem. Tried everything keeps coming back. This needs fixing Sonos!!!

Just thought I’d add my experience to this thread as I have the same issue on 14.8

I spent time chatting to Sonos support and in the end hardwired my Arc to my router (fortunately for me they are close to each other) and this has resolved the issue, so it definitely appears network related, but more likely Sonos rather than Wi-Fi as it was working before latest updates.

So for now, hardwire if you can until it gets fixed.

I have this problem. I reset the wifi and it sometimes helps it (for about 12-24hrs) and then I have to do it all again.

 

how is this not being addressed?

I’m not seeing how resetting the WiFi would help here, as the Sub uses a direct 5Ghz wireless connection between itself and the ‘bonded’ main player - although you might perhaps have wireless interference issues around your actual devices, perhaps? .. IMHO, I think trying to explore 5Ghz interference and maybe try to look closer at that issue, might possibly be a more effective longer-term solution.

Think I’m getting this sync issue as well, I have arc and sub gen 3, I noticed it during the last episode of Night Sky on Amazon prime during the end rolling credits.

If you do encounter the issue again, at any point, it might help the Support Staff if can submit a Sonos System Diagnostic Report asap and then contact/chat to them via this LINK

Same here. It seems to come and go. Today not only my sub but also the surround-OneSLs are affected.

Same here for 4 weeks, with lots of support tickets and diagnostic numbers, regards, a sad owner

I also have surrounds and sub delay echoing after the Arc.
I have read articles saying Sonos are denying there is a problem with this latest update but there obviously is.

Please Sonos rectify this as switching off the Sub and surrounds is not the home theatre setup I thought I was investing in with the Arc.

I have never had lag echoing with my Sonos Sub 3 but I did get it when my 2 Sonos One SL's were playing surround sound, say, from a movie but since the last update (14.8.1) thankfully this problem has gone away!

 

When playing movies I just used to turn off the surround speakers as it was doing my head in which kind of defeats the purpose of buying surround speakers!

 

I just wish that the Sonos app had a way of rolling back the last software update like Windows used to do when I had a PC around a decade ago!

Same issue. Just noticed it tonight and wow it’s annoying. 

Same here.

My system is on 14.6.1. Would a new software version not have cured this?

Just got my Arc and Sub 3 in the mail today and I’ve experienced this half a dozen times already. This was my first Sonos purchase and I’ve gone from excited to disappointed very quickly.

I have same issue with subs and rear speakers being delayed. My setup is arc+2 subs+amp and 2 ceiling mounts for rears.

Yeah i get reverb from sub and surrounds - it’s really obnoxious. I’m ready to throw this garbage in the trash and go Sony.
