I have the playbar and 2 Sonos one SL connected. However, there is no sound coming from the rear speakers. The playbar sounds great, I can only mute and control the sound from the SL speakers. How do I get them to all play? This is driving me crazy I’m about to return this whole system.

r.perez0622, 


That’s what I would have done too. If you need any further help when you get the Boost, then post back here and I/we will do all we can to assist. 👍

Well @Ken_Griffiths and @Jean C. the Sonos boost is a saver and has made me a believer. The system sounds amazing. The boost really did the job. The setup was easy. I had to uninstall everything and do the boost first. Once that was done, I tuned the room and now they are all synced together. It works flawlessly. It’s like my own movie theater surround sound. Now, I just need to place them where I want them. I will definitely get the sub to complete the system. Sonos has a customer for life. Thanks for all the help.

Ah that’s great news r.perez0623 and credit is due to @Jean C. at Sonos Support for identifying the issue quickly from your diagnostic. I also run my Sonos system with a Boost/SonosNet device too, it works really well here… best way to go, I think.

I also think you will love the Sonos Sub too if you do decide to add that to your setup,further down the line. The sub made such a difference to our Home Theatre System here.

 

All’s well, that ends well, eh? Thanks for letting us know how things turned out for you.👍

Thanks so much for that information, @r.perez0622 .

Welcome to the Sonos Community, by the way, and thank you for reaching out with your issue. 

You have two of my favorites in your current set-up.

You seem have an ISP provided Askey router, Ruckus access points and a Sonos surround system on Wi-Fi. 

Is there any way that the Playbar can be wired into your network via Ethernet?

Have you had your Ruckus APs configured to allow multicast rather than their default unicast?  

They actually have a helpful support article on their website concerning Sonos systems. 

If you are able to hard-wire the Playbar, it will prompt your system to broadcast Sonosnet and should neatly sidestep these kinds of issues.

Hi @r.perez0622,

A Boost should be able to resolve this issue as @Ken_Griffiths  and Ruckus both suggest.

Its job is to be the thing wired into your router when nothing else can be. 

We’re here for you if you need assistance setting this up, please don’t hesitate to reach out. 

 

Also whilst you’re scrolling down the device list, just ensure that both the Sonos One SL’s are listed with their IP addresses etc. It will be interesting to also establish if the surrounds 'wireless mode' is set to WM:0 or WM:2?

The two speakers are WM1 

Well that indicates the two SL’s are not 'bonded' to your Playbar … is it a case you may have originally 'grouped' them with the playbar instead and they have ungrouped on TV playback? … I suspect that might be what is happening here?… Did you bond them through the Playbar Room Settings using the “Add Surrounds” option?

Agreed. That was my suspension as I mentioned much earlier in this thread.

Hi @r.perez0622 

Everyone here is offering sound advice. 

If you are still stuck, don’t hesitate to submit a diagnostic report from your Sonos system. 

If you post the confirmation number here, I’d be more than happy to look it over and offer a tech’s-eye view on what’s going on.

I can’t wire via Ethernet as my router is downstairs and the playbar is upstairs.

Hit the wrong icon. Darn iPhone screen 😡

r.perez0622,

i think adding a Sonos Boost to your setup would make things far much easier for you and if would mean less ‘command line’ configuration of the access points and ports as mentioned on the Ruckus website link for a Sonos ‘standard mode’ setup. 
 

The article appears to strongly recommend you wire one Sonos device to the main router and I must admit that’s the route I would personally choose to go down too with a Sonos Boost, but the decision is yours.

Yes, when you ‘group’ other Sonos Rooms with a Sonos HT setup there is a 75ms audio buffer delay for the stereo TV audio-out to the group, but only a ~30ms buffer for the TV HT audio, which obviously plays as quickly as possible for TV lip-sync purposes, so you may indeed hear an echo for TV audio .. you won’t get an echo when playing music audio from the App.
 

There is a setting (slider bar) within the Playbar Room settings called ‘TV Dialog Sync’ that can be used to resolve the echo when playing the TV audio.

 

i will just add though that the TV audio really works best when your speakers are ‘bonded’ as surrounds, rather than ‘grouped’ and I would suggest if you eventually do choose to configure your access points, or get a Boost and do that, that you also switch the music audio playback  from ‘ambient’ to ‘full’ in the Playbar Room room/surround settings as all these things will eliminate any echo for the TV audio and the music will sound great too.

I’m going to try the boost. I will buy it tomorrow and try that for a final solution. Everything I read, leads me to the size of house and WiFi extender is the cause of my problem. I’ll try it out tomorrow and see if it resolves the issue. I would hate to return everything cause of the WiFi extender I have. Thanks again for all the help.

What source are you playing and is it in DD5.1 format? 

Userlevel 7

Thanks for replying. Based upon what you are seeing in the app it looks like @John B is on the right track. If the source is not sending surround material then you won’t hear it. 

You might also check out the trouble shooting tips in the link:

Let us know how things sort out.

Cheers!

Factory resetting everything will wipe out playlists and settings and more. I think more troubleshooting should be attempted before trying that

It’s full not ambient. Both of the Sonos One Sl speakers worked without being set up to the playbar, but once I did that no sound. I tried watching a 4K movie through my Xbox one S. I have the digital optical cable connected to my Xbox. Still nothing. 


I'm still in agreement with @John B that it’s the source setting or TV sound menu. All sources Xbox, AppleTV etc., must be set to send DD5.1. The TV must be set to send DD5.1 or PCM.

All of your sources should be connected to your TV via HDMI direct or through a HDMI switch. The optical connection for audio should be between your Playbar and TV. 

At this juncture I suggest a Factory Reset of all Sonos. Connect your sources to your TV via HDMI direct or via a HDMI switch. Follow the instructions in the links below:

Factory Reset *

Home Theater Setup with Playbar and adding surrounds **

 * There are consequences to a Factory Reset please read the instructions carefully.

 ** After a Factory Reset you are setting up a NEW system

 

I’m getting DD 5.1 according to Sonos on the playbar. Still no sound from the SL

Are you seeing that 5.1 audio input when you navigate the Sonos App to “Settings/System/About My System” and scroll down to the Playbar in the device list? (Next to the Audio In entry?)

Also whilst you’re scrolling down the device list, just ensure that both the Sonos One SL’s are listed with their IP addresses etc. It will be interesting to also establish if the surrounds 'wireless mode' is set to WM:0 or WM:2?

Should I just remove the surrounds? I feel like I have tried that already. I thought they are bond

Can you perhaps post some screenshots, so we can see what you’re seeing..it would be helpful to see the following…

  • Sonos App ...‘Rooms Tab’ (off main bottom bar)
  • “Settings/System” (showing your Playbar Room and any other Sonos Rooms
  • The actual surround Settings in the Playbar Room 

AjTrek1 .. Yes, there is no way the speakers are 'bonded' to the Playbar if they are WM:1 .. so something is wrong here. 👍 Hopefully the screenshots from the OP will help.
