Losing control of audio device

Description of Issue

I’m having trouble with all of my Roon zones, whether I’m connecting via the Sonos network or via Airplay.
A track plays for a few seconds before it stops and then I get the message ‘Roon lost control of the audio device’
My Sonos network is working fine and other devices work fine on wifi.
I suspect the issue may be with my Roon core and a recent update to Mac OS 11.7.8?

@Jez_Hall we had this issue a few months ago, please see:

Sonos - "Roon lost control of the audio device" after Sonos Update [Resolved: Update Sonos Firmware]

Roon Core Machine Apple M1 Macbook Pro / 8 GB Networking Gear & Setup Details Google Mesh Network / No VPN Connected Audio Devices Sonos / Play:5 / Play One Number of Tracks in Library less than 10,000 titles Description of Issue Since updating to the latest macOS (RoonCore) and the latest iOS and iPadOS version (RoonRemote), RoonCore cannot establish a Sonos streaming connection to some Sonos products. Before this worked without problems. The connection via Airplay works.

Hi - Thanks but I’m not sure this is the same issue as I am on Sonos version 15.5. I suspect the Apple OS update which seemed to coincide with the Roon issues, but I could be wrong.

All right - I wish you good luck in finding the cause!

Can anyone tell me how I can tell whether my Sonos amp is using wifi or ethernet to connect with Roon? I have a jumble of very old Ethernet wires throughout the house and am not sure if I have connected correctly from the router to the amp?
Thanks

[Jez_Hall]

Thanks. If you could confirm where please. I couldn’t find that info.

A basic question would be: Did you connect and log-in it to the WiFi in the first place? I know, but it needs to be asked… I R engineer…

Another place to look is in your router “clients” page to verify what IP the router has given to the wired and wireless connections for the Sonos. Then look in Roon under Settings/audio and see what IP Roon is using for the device.
Here’s a screenshot from my system (I do not have a Sonos but Roon should show it the same way):

If you can’t access you router (or don’t know how to) you could look in Roon under settings/audio the see the IP, then unplug the ethernet cable and see what happens. If the sonos goes away (or changes to a different IP) then it was using ethernet.

Hi Many thanks. I have been able to establish my Sonos amp is now connected via ethernet.
I’ve also been able to prove (through process of elimination) that all the issues with Roon losing control of audio devices is down to Roon Core and not any WiFi AirPlay issues.
So I await an update from somewhere??

If you have an iPhone or iPad the Phonos Plus app is a great way to quickly obtain details of Sonos gear on your network, including whether individual devices are wired or wireless.

Many thanks. I didn’t know about this app - very helpful

Hi @Jez_Hall ,

Apologies for the slow response here. Are you having issues on other zones such as System Output (Core internal speakers) or is the behavior limited to the Sonos zones? I noticed you mentioned having both Core and Sonos on WiFi, is the behavior the same if you try to plug them in via Ethernet cable instead?

[Jez_Hall]

Thanks for your reply. Strangely the issue I was having seems to have resolved itself. I would feel a bit more confident if I knew how, but I’ll settle for ‘working’ right now.
