One speaker from stereo pair stops working

Hi,

I have a pair of Play:1's in my kitchen, configured as a stereo pair.

Several times now (maybe, on average, once every 2 weeks), the right speaker stops working. Once it stops, it never comes back and the only way I can get it to come back is to separate the pair, and recreate it. This (so far) has worked immediately every time, so it appears the speaker itself works fine (in fact, when I separate it, I can always play music directly on it).

I have a couple of other pairs of Play:1's in my setup, and only ever get this problem with the same, right, speaker in my kitchen zone. Nether speakers are wired.

Any ideas why I keep getting this problem? For Sonos support, my Diagnostic confirmation number is: 603946054.

Thanks.

Hi, also have this issue. Right speaker in l+r pair keeps going quiet. The touch controls and Alexa on this speaker will still control the system when it’s quiet though. It’s in the same room as the WiFi router. 225545706 Is diagnostics number. Thanks

Typo diagnose number should be 1572755521

Thanks for sending in the report. There's wireless interference from nearby networks running on the same channel as your own. This is making it hard for your speakers to stay connected, and your right speaker has lost communication with the rest of the system. Also, you have 2 access points which are running on different wireless channels. Please try changing both of your wireless access points over to wireless channel 6 and test things out.

Same problem here. Diagnostic confirmation number: 1086432769

It looks like you recently switched your system back to the mesh configuration by wiring in your Bridge. There are still some errors relating to connections to your wireless network. Please head into the Sonos app and go to the settings menu. In the advanced settings page you can click wireless setup to find the option to reset your wireless credentials. Please try this, then reboot your Sonos speakers. Send along a new report if any issues continue.

Hi there,

In your report it looks like you have a Sonos 5.1 surround setup. I don't see a stereo pair. If the stereo pair of speakers isn't showing up in the app, please follow the steps in this guide to get the speakers reconnected.

If you're having trouble with the speakers in your surround setup, take a look around and in between the speakers and see if there are any third party wireless electronics which could cause interference. Common sources of this type of interference include cordless phone bases, wireless cameras, wireless baby monitors and wireless printers. Try moving away from your speakers any such devices you find.

It looks like there's a bit of interference showing up from a secondary wireless network your router is creating that is on the same channel as your main network. Try changing the network with the "-X" at the end over to channel 11 and see if that helps.

I have the same problem. Two Play 5s (1st gen) configured as stereo pair. Right hand speaker (always the RH) often fails to start when system activated. Won't restore of its own accord. Fix is turn off power, wait a bit and then turn on again. Logged a fault with Sonos. As always, their answer was "wireless congestion", change WiFi/Sonosnet channel(s), move all RF sources nearby. Done all that. Have also locked specific IF addresses on all Sonos units but still the problem persists! Surely Sonos can fix this?

Hi there,

Wireless interference is the most common cause of a stereo pair falling out of sync. Please submit a diagnostic report after this happens, but before any reboots. Reply with the confirmation number, I can take a look for you.

I have the same issue - two play 1's - the right hand side one often doesn't play. Diagnostic report 1256881205 - can you help? Thanks

I am having the exact same issue. I have two Play 1 pairs (plus two singles) and both pairs keep separating. The fix above works, un-pair then re-pair but this is annoying to do each day.

Diagnostics number is 1242515697.

My problem only started with the latest system update.

I have set fixed IP addresses and changed the wi fi channel, with no success.
