Music cutting out, skipping songs, unable to stream with 12 Sonos devices

Providing a little more info about what seems to work well and what does not work. One of my Sonos rooms is Office which is comprised of a Connect attached to network by ethernet and connected to two self-amplified speakers. When streaming music to Office alone, I seem to be able to play some of my Playlists from multiple sources, including TIDAL HiFi streaming- but even in this one room TIDAL songs will not play to completion, they will skip to next song, etc. The grouping I would like to use most often is a collection of Bedroom (Playbar/etherrnet and 2 Play1/wireless)+Bathtub (Play5/wireless)+Shower (Play5/wireless)+Living Room (2 Play1/wireless and Sub/wireless)+Pantry (Play 3/wireless) and this group is unable to play without stopping/skipping/errors.

When it acts up submit a diagnostic and post it here or call it in to Sonos support.

Hi, Stanley_4. Thanks for your feedback. The Sonos system is continuously acting up and I submitted a diagnostic code in my original post above. I just submitted another diagnostics while the problem is occurring and that code is 154608053.

Hey there, gadgetnut Thanks for posting your diagnostic report. I am seeing quite a bit of wireless latency on the Sonos network. This usually points to wireless interference. I see you are using a Ubiquiti network, are any of the Sonos players nearby any of the satellite units?

Hi, Keith. My home has two Ubiquiti access points indoors. One of the Ubiquiti access points is in the Living Room and has a Play1 connected wirelessly located about three feet away. The other paired Play1 and Sub in living room are 15 feet away or further. The living room also has a Boost connected by ethernet about seven feet away from the Ubiquiti WAP. The other Ubiquiti WAP is in an office on the other side of the house, where a Connect connected by ethernet is about twelve feet away from the access point. As I said, I have changed Sonosnet wireless channels from 1 to 6 to 11 without long lasting improvement and I have added and deleted my WiFi network credentials, also to no lasting improvement. Thoughts?

Understood. What else is nearby the BOOST? I am seeing quite the fluctuating noise floor which means that it is picking up a wireless signal from another device which is interfering with its ability to serve the rest of your Sonos system.

Hi, Keith. Since I have several Sonos devices (Playbar, Connect) connected by ethernet, I'm not sure I even need the Boost at my house. The Boost is centrally located in the home, in a Living Room in open air on top of an AV cabinet. Within three feet of the Boost are a wireless phone base station, AV components, and a managed ethernet switch. I've tried using Sonos with the Boost disconnected, no improvement. I could relocate the Boost or move the telephone further away. Suggestions?

Thanks for the helpful description. I'd like to learn a little more about your network and how Sonos is currently plugged in.
Since I have several Sonos devices (Playbar, Connect) connected by ethernet, I'm not sure I even need the Boost at my house. How are these other Sonos players plugged into the network? Are they plugged into the Access Points or into the main routing unit (connected to the Modem)? Are any plugged into the managed switch?

Thanks again in advance.

My network structure is: Xfinity Gigabit Gateway>Ubiquiti UniFi USG-3 (router)>UniFi 24 Port Managed Switch>UniFi AP access points and ethernet-connected clients.

Here is my understanding of the Sonos connections.

PlayBarBedroom connected via ethernet to UniFi 24 Port Managed Switch Port 10. Play5Bathtub, Play5Shower, Play1BedroomLeftSurround, Play1BedroomRightSurround, and Play1YardFrontRight appear to be connected wirelessly via Sonosnet to this PlayBar.

Sonos Boost connected via ethernet to UniFI 24 Port Managed Switch Port 12. Play1LivingRoomRight, Play1LivingRoomLeft, SubLivingRoom, Play3Pantry, ConnectYardBack, ConnectScreenRoom, Play1YardFrontLeft appear to be connected wirelessly via Sonosnet to the Boost.

For the room known as CJK Office, ethernet from UniFi 24 Port Managed Switch to UniFi AP-Pro access point then ethernet to an unmanaged switch for the office devices including ethernet to ConnectCJKOffice.

In the UniFi USG-3 (router), I configured DHCP reservations for all Sonos devices. I have restarted the gateway, the router, and all Sonos devices numerous times. Playing music in a single room can sometimes work fine but playback to multiple rooms simultaneously is predictably unstable. It feels like adding the Living Room to a play Group is destabilizing.

Understood. Whenever Sonos is routed through managed switches, things get a little odd. Ideally, we want Sonos to have full control of the data being sent through SonosNet. Is there any way to plug the Boost directly into the Ubiquiti UniFi USG-3? If you unplug the other Sonos devices from the network leaving just the Boost hardwired into the USG-3, we should be able to get things in a better position. At that point, we will need to take a closer look at the wireless interference. This is because the AP's will likely be adding interference to the wireless environment Sonos will be using to talk from player-to-player.

If this is possible, please test the audio for about 20 minutes and then submit another diagnostic report. Be sure to reply here with the confirmation number, and I'll be happy to take a look and see where we stand.
