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

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.

My setup is arc + one SL as surrounds

And I also have to experience the surrounds getting out of sync .

This has to stop.

Sonos….. we need an update with a correction of these issues

I have exactly the same problem. After resetting, rebooting my WI-FI and unplugging power repeatedly it still doesn’t fix the problem. The sub will just come on randomly and then go into this reverb mode. Come on Sonos, we didn’t pay three times the amount for a sound bar and sub to experience bargain equipment reliability.

Same issue here since 14.6, but with rear Play:1’s to Sonos Arc. Sometimes they’re delayed, sometimes they just stop working entirely, I’ve had them distorting and garbled. I must have re-added the surrounds about 7/8 times now, power cycled the Arc triple that, solves it for a very short period then it comes back. Pretty disappointing there’s been no fix, and the mis-mash of statements and denials from Sonos means it’s starting to feel like amateur hour, which it really shouldn’t for a product like this.

You are probably dealing with the same problem as these users:

 

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 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.

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.

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

Same here.

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 

HTH

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

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

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.

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.

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. 

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.

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.

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

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

Thanks @Herm212 and @GuitarSuperstar.

I read that thread and it’s possible the symptom I’m experiencing is related in some way, I’m not sure.

In my case I’m not losing audio on the subwoofer or surrounds -- the only manifestation I’ve observed is that the subwoofer audio is slightly delayed relative to the ARC.  I suspect that the audio synchronization software has a bug, but that’s just a guess as to what is going on.

As an example….last night I went to bed with the system playing correctly -- meaning good synchronization between the ARC and the sub.  This morning when I turned on my TV to watch some news I could tell that the subwoofer signal was lagging the ARC -- bass notes were slightly delayed relative to the rest of the audio.  I estimate this signal lag is a few hundred milliseconds.

I power cycled the ARC and normal sound was restored after it restarted.

(Side note:  This morning I also added a WiFi power outlet for easier power cycling of the ARC as a band-aid until Sonos is able to released updated firmware.)

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.

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 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 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!
