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 @joeser

Welcome back to the Sonos Community!

I’m sorry to hear of this sync issue you are having with your pair of Era 100s - it does sound annoying!

While playing, and while the speakers are out-of-sync, please submit a support diagnostic and reply here when done, but please do not share the number given - I’ll be happy to take a look and see what I can see. After submitting, feel free to do what you need to do to get it behaving again.

Hi @Polologt

Welcome to the Sonos Community!

Please do the same, thank you.

I submitted a support diagnostic. As usual within 1 day of setting up the stereo pair the echo effect was back.

Let me know if you need anything more.

Hi @joeser

Thanks for that! Could you please tell me what you can about your router and Internet Service Provider?

Also, how far apart are the speakers physically?

Hello

I have two ERA 100 used in the same room, in stereo.
The distance between the two ERA 100 is 5m.
The distance between each ERA 100 and the router is 3m and 5m.
The problem I'm encountering: the ERA 100 on the right of the stereo pair cuts out for 10-15 seconds, then reconnects.
Yet it's the one closest to the router.

The problem occurs under the following 4 conditions:
When listening to music files on my iPhone.
Streaming via a RADIO application.
When using the SONOS application with Spotify.
When listening to Spotify self in Airplay.

There is no time cycle, it happens randomly.

I've redone my entire configuration.
First time configured the right one first, then left, then stereo.
Second time I set up the left one first, then right, then stereo.

The two ERAs : First is dated late August. Amazing sound. Then a second for stereo early September 2024.

Bests regards

Hi @Polologt

Thanks for that information. Could you also recreate this issue and then submit a support diagnostic, letting me know here when you have done so? Please also include details of your router. Thanks.

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.

This evening a update is arrived in my two Era 100.

After the update, I try to restart the setup from scratch and inverted physically the two speaker.
The two speaker are now in stereo again.
… And The problem is the same, the right speaker no lounger produces sound after a wile, then sound came back.

So, it’s a software gestion of the right side, (It reassures me that it is not a hardware problem).
It doesn't matter which of the two speakers is configured on the right.

please fixes this.

Hello.

The right ERA 100 of the stereo pair disconnects. I tried by electrically disconnecting both and reconnecting only the right one.

I go in app SONOS to see my « right » ERA , I see this : "this speaker is not part of the stereo pair. Separate the Stereo pair". (screenshot here, in French).

if i reconnect the electricity, right ERA reconnects to the network and appears in the stereo pair, produce music for a few seconds, Today it is hell.

With my tests, I am convinced that the problem is software, but please, do something.
