Era 100 stereo pair losing sync

46 replies
1811 views

Since the new app was introduced, my pair of Era 100 will not stay in sync. The delay from one speaker to the other keeps increasing. After setup, withing a day when I turn them back on there is an “echo” due to delays. Within a couple of days they get even further apart in timing to where it is totally unlistenable.

If I reset my router, this most often seems to fix the problem, but I don’t want to have to do a twice daily reboot of my router, nor was this necessary at all before the Sonos update to the new system.

If I try to remove the stereo pair and then recreate the pair, then only one speaker will have sound in the pair.

So I end up power cycling the speakers, rebooting my router, have issues with the speakers being found, then finally put them back into a stereo pair, but this is crazy. I have wasted so much time on trying to get these speakers to stay working as a stereo pair. None of the updates have made it any better.

I have tried giving the speakers a fixed IP address assignment based on their MAC, but this didn’t help at all.

As individual speakers they work fine, but that isn’t why I bought a pair of speakers.

I installed a new Asus tri-band router to replace the Telus Actiontec, using “Tri-band Smart Connect” (all bands have the same SSID and password), and the Sonos speakers were reconfigured onto this network and have been working without issue so far.

I can access them from any device connected via 2.4G, 5G, 6E, or Ethernet cable.

So definitely the Telus Router has been the source of my issues.

Hope this helps someone else who is having trouble using Telus equipment.

Hi @Polologt

Thanks for all that information, but am I right in understanding that your stereo-paired speakers are not going out of sync with each other? That one is just cutting out instead? If this is the case, then you are off-topic for this particular thread.

I took a look at your diagnostics anyway, but as there is a speaker missing from them, I can’t determine much. In addition, it looks like you have reset your entire system since their submission, so the diagnostics are no longer relevant anyway.

I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports - I hope they are able to assist.

Hi @joeser

In my case the router is a T3200M supplied by my ISP Telus. I am on their fiber network.

The speakers are about 6 feet apart, each side of a bed.

In case it matters, I am talking about listening to Sonos radio stations, I haven’t yet tried if other sources have the same problem.

Thanks for that additional info. Could you please try some other sources? I doubt it will make any difference, but it’s just so we know one way or another. Thanks.

This evening, I reset up the stereo pair, which worked fine with Sonus radio, but immediately when I did a bluetooth connection using the right speaker, only the right speaker was playing sound.

I tried line in on the right speaker, sound only came from the right speaker.

I went back to Sonos radio, sound would only come from the left speaker.

I tried Spotify, sound would only come from the left speaker.

So I removed the stereo pair, and tried reconnecting the stereo pair. Sound only came from the left speaker still with Sonos radio/ startup sound for stereo pairing.

I rebooted my router, then all sources worked for stereo sound again with no sync issues. (Sonus radio, Spotify, bluetooth, line-in: all good)

I will let you know in the morning how the sync drift is working, but I wanted to type this problem while the memory was fresh.

OK, I tried to use different sources to check the sync drift, but once Sonos radio is showing the echo, when I try to use other sources it “breaks” the stereo pair like my post above.

Different sources come out of only one or the other speaker, even when I go back to Sonos radio, there is no more stereo sound even though the Sonos app still thinks there is a stereo pair.

Touch on/off control and the volume slide still works using either speaker.

I think I find for me the solution : gone in setup of my router, and split 2,4 & 5 Ghz Wifi.

no problem of synchro from around 24h !
whouaw !

Hi @joeser

Thanks for performing those tests.

I’m starting to think that there might be a speaker at fault now, but the only way of ascertaining whether that is the case or not is with some in-depth troubleshooting.

There are some things that can be tried, but I’d rather see you do them while on a call so that you don’t have to repeat them again in order to prove anything later - at this point, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports at each stage. I advise informing the agent you speak to of this thread, so you don’t to repeat too much. The following search in Google will take them right here: “era 100 stereo pair sync”.

I hope they are able to help.

Hi @Polologt

That’s great to hear - thanks for updating the thread!

Also a bit confusing, as that shouldn’t make the slightest bit of difference! Worth trying, however, @joeser - split the 2.4 GHz and 5GHz bands in the router’s settings so they don’t have the same name. This will force the speakers on to the band for which they know the credentials. I should point out that in your diagnostics, both speakers were on 5GHz, so I am not convinced, but if it worked for @Polologt, then I guess it’s worth a try.

It took me a while to find where 2.4/5G splitting could be done, on my modem/router it was under “SmartSteering”.

I will try again with the 5G network and see if this fixes anything.

I also turned off “WMM Power Save” since power consumption isn’t a worry for any wireless devices I am using just in case the “dozing” could be causing any issues.

If these two changes don’t fix things I will give tech support a call.

I am not that hopeful as everything used to work with the older Sonos system software/firmware, but who knows.

Still working here. Youhou !!!

With sonos app or Spotify, playing my own music from iPhone, my wife selecting from her iPhone, pause, local Radio, everything ok.
OMG they’re working for what they are made for.

I hope this working for you.

So, 2,4Ghz & 5 are activated and have different SSID names. « Wifi-###-2.4 » & « Wifi-###-5.
then Sonos app ask for an update of network settings.

The separated 2.4 and 5 Ghz bands didn’t help, speakers are back to an echo chamber this morning.

I am giving support a call to see what they are able to do.
