ONE SL - Does not reconnect when TV turned back on

Your One SL’s are bonded as surrounds to the Playbar? Or are they set up as separate speakers and grouped with the Playbar? When you turn off your TV do you cut power to the Playbar and Sub only?

You can find more about grouping here: https://support.sonos.com/en-us/article/group-and-ungroup-rooms

Does the Playbar stay powered on when the tv is turned off?

Are the One SL’s grouped with the Playbar or bonded as surrounds?

If you turn off the tv and stream music to the Playbar room, do you get sound from Playbar and the Ones?

Can you stream music just to the Ones?

It sounds like it.

Hello All,

Thanks so much for the quick responses.  You rock!  And Merry Xmas eve.

To answer your questions and comments:

As stated in my original post ONLY the TV gets turned off, the player and sub stays on.  I just confirmed that.  Remote turns the TV off and all other devices stay plugged in and on. 

RE: Are they “bonded” to Playbar?  That is a good question.  I do not know.  Everything is set up wirelessly and the One SLs were added later so they are likely set up as independent?  I will read the link provided by 106rallye and see how I might resolve.  

Since the answer is YES - sub and playbar stay ON when TV is turned off (and they always reconnect with TV no problem when TV is turned back on), if you have any other words of wisdom please share.  

“Bonded” means set up as surrounds, and would show up as [PLAYBAR’s room name] (+LS+RS) in the controller.

”Grouped” means these speakers are set up as a stereo pair in another Sonos ‘room’ (which could be the same room name), and would show up as [Room name] (L+R)

The distinction is important to answer the issue properly. 

Sometimes, asking specific questions - even when the op thinks they’ve already provided the answers - can help clarify the problem and lead to a solution. 
 

You’ve not yet answered all of my questions: can you stream music just to your Ones? Does music come from One’s and Playbar? 

They are indeed bonded as you can see in photos.

Here are a few more variables:

1.  When the TV is turned off, the One SLs actually stay connected for a small amount of time (exact time unknown).  When I turn the TV back on, let’s say 10 minutes later, the One SLs work fine and are synced.  
    
2. It appears when the TV is off for longer periods (many hours?) that is when the One SLs do not reconnect or resync, even though no other network changes have occurred during that time.  
    
3. I read the very simple grouping and ungrouping link and it’s very easy to understand but my Sonos app simply doesn’t display grouping and ungrouping (small monitor icon) in the same manner either on iOS or Windows?  I can’t find anywhere to group or ungroup?  I looked at every option.
    
4. The only setting I found that may be related is “ungroup on autoplay”, under Home Theatre, which was previously on.  I just turned it to the off position to see if nothing is impacted after the TV has been off for several hours.  
    
5. a couple photos attached that may be helpful?

Thanks again all - really appreciate it!  Getting this resolved will make my 8-year old and 7-year old’s Xmas for the surround speakers to always stay on and for me to not have to turn everything off and resync it all the time.  

Hmmm… From that info: yes, they are bonded as surrounds. 
 

Have you tried powering down the whole system and restarting the system in the order: router, Playbar, Sub, surrounds, waiting till rack has fully restarted (especially the router and wifi signal) before starting the next? If so, maybe de-bond the surrounds and then re-add them? Or generate a diagnostics within a few minutes of the issue occurring, and then contacting Sonos support to discuss it? 

Yes.  Many, many times.  This method indeed fixes the issue - short-term.  Everything works great until the TV (only the TV) remains off for x hours.  At that point, the One SLs somehow become unsynced, while Play at and sub do not, and following your above-stated method always resolves the issue until the next TV power cycle off for x hours?  
 

It’s a baffling puzzle for sure!  I haven’t tried any logs shortly after yet, only because the issues doesn’t start until an unknown time after - x hours?  The immediate logs after rebooting everything may show as fine?  
 

Thanks again!
