Hi There,
I tried the form:“Technical Support Request”, but this is a dog to go thru and does not address my issue. Better put an AI chatbot here with access to the solutions library.
Since a few days I cannot use my SONOS endpoints anymore. When selecting them I get the message: “Roon lost control of audio device”
This happened out of the blue as I have not changed any settings or hardware. Both my SL1 and Beam experience this issue. Using the SONOS app still works. My Devialet still works with ROON, which is my go-to device.
I have powered down all
SONOS SL1: Version 16.7 (build 84.1-63110) Hardware version: 1.28.1.6-2.1
SONOS Beam: Version: 16.7 (build 84.-63251 Hardware version: 1.23.1.10-2.1
ROCK v 2.48 (build 1517)
OS: Version 1.0 (build 259)
Running on Intel BOXNUC8I5BEH2
Connected wired to Router
SONOS running on my own wireless network with router set in slave mode and wired to main router.
As said, this setup has been like this for at least a year.
Researching this issue i also found this: (Sonos causing high CPU usage after playback stopped (ref#HMNFG1) [Roon Investigating] (Tracking thread) - #46 by Brian_Wood), which was closed unsolved??
I had stuttering music on my Devialet a few times, which is odd as it is wired to the same router as the ROCK.
Rebooting the network and routers did not do anything. I checked the NUC and found it hot and fans blazing, while I was running just a single stream. Rebooting the NUC was the only solve. Since its been ok.
I did have the issue in prior years that out of nowhere the fans started blazing. I “solved” this by removing the NUC from my office and placing it in my tech room.
Reading up though, it seems to be linked to SONOS streams. As these do not work anymore for me, the NUC is cold and quiet. Not the solve I was looking for though
