Describe the issue

After the Roon 2.6 update, all Sonos streaming fails; audio cuts after 10-30 seconds and then the audio device is lost. No changes were made to the Sonos system or network hardware. The Sonos:5 seems to work if streaming via Airplay 2, but the other Sonos devices require Sonos streaming and that is now broken. The only change was updating Roon.

Describe your network setup

Ubiquiti Cloud Gateway Fiber -> fiber connection to switch -> ethernet to Mac mini M1 Roon server. Sonos is on wifi.

Hello @nathanael, and welcome to the Roon community!

We are sorry to hear that you are experiencing these audio dropouts with your Sonos devices. Let’s gather a bit more information so we can help get your system stable again.

We can see from our system diagnostics that your Roon Core was updated to version 2.6 on February 21st at 15:25. Did these dropouts begin immediately after that update was installed, or was there a delay of a few days before the symptoms started?

To help us narrow down the cause, could you clarify a few details about how your Sonos devices are communicating?

• Playback Method: When the audio cuts out, are you playing to a single Sonos speaker individually, or are you playing to multiple Sonos devices that are grouped together in Roon?
• Connection Type: You mentioned that Sonos is on Wi-Fi. Are all of your Sonos devices connecting directly to your Ubiquiti Wi-Fi network, or is one of them wired to the network to create a dedicated SonosNet mesh?

The most helpful step right now is to catch the error in the act so we can review the diagnostic logs from your Mac Mini.

Could you please reproduce the issue one more time? When the music stops playing unexpectedly after that 10-30 second mark, please note down:

1. The exact local time the audio cut out.
2. The track name that was playing.

Once you reply with that timestamp and track information, we will pull your server logs to see exactly why the connection is dropping.

Thanks for your response. To answer your questions:

1. Yes, this started happening immediately after upgrading to 2.6, although it has been intermittent. On some days, I cannot steam any music via Sonos streaming but today I was able to play some tracks though the issue occurred at 8:14am ET, playing Verse by Rhye.
2. This happens both when playing to a single Sonos speaker or a group. Sonos grouping seems broken anyway but that is a separate issue.
3. All of the Sonos speakers are connected directly to the wifi network via wifi.

Hi @nathanael,

Thank you for your post.

Here’s what we see in logs. A particular Sonos Play:5 in a grouped Zone stopped lost its network connection to Roon Server temporarily, and Roon had to reconstruct the Zone. This caused playback to stop across the whole grouped Zone:

03/13 08:14:01 Warn: [zone Library + Library (Sonos PLAY:5 Gen 1) + Kitchen (Sonos PLAY:5)] Track Stopped Due to LostEndpoint
03/13 08:14:01 Info: [zone Library + Library (Sonos PLAY:5 Gen 1) + Kitchen (Sonos PLAY:5)] OnPlayFeedback StoppedLostEndpoint

It’s worth noting that two things occur right beforehand. First, Roon Server logged an unrelated critical exception that occurred during some metadata indexing. This broker interruption might have interfered with the network connection. At the time time, multiple Sonos devices reported to Roon that they stopped receiving network packets and had to reset their UPnP subscription renewal.

I recommend trying two things:

1. Try hardwiring one of the Play:5s via ethernet. This will activate SonosNET, permitting the Sonos endpoints to forward network traffic to/from one another via a dedicated channel.

2. Please try configuring the following in your Ubiquiti settings:

• Disable IGMP snooping
• Turn on multicast enhancement
• Disable client isolation

3) Lastly, please reproduce the issue playing to a single Play:5 (ideally, the one you’ve hardwired in step 1). Let us know the name of a track that drops out. We’ll pinpoint the event in logs.

Thank you!
