I suggest you submit a diagnostic within 10 minutes of the next occurrence and post the reference ID in your post. After that call Sonos tech support as they can view your diagnostic and give answers about what is causing the issue.

Open the Sonos app > Settings > Support > Submit Diagnostic

Hi @OldMonk250,

Please note that this is a Sonos user-community. You need to contact Sonos Support Staff if you hope to get some information about that diagnostic submission reference. You can contact them via this LINK.

Alternatively, if you prefer to describe the issue you’re seeing in much more detail and are able to describe your network/Sonos setup, you may also find some community users here who may be able to offer some suggestions for you to try, such as changing your router or SonosNet wireless channel and offering tips on how to reduce interference. In fact to maybe help get you started with troubleshooting the issue yourself, have a read of the below Sonos Support link:

This community support is completely useless

Community support is free, Sonos is kind enough to provide the forums for us and an occasional visit by Staff.

If you want Sonos support contact Sonos Support, not a bunch of users that like playing with our Sonos and helping others.
