Sonos causing high CPU usage after playback stopped (ref#HMNFG1) [Roon Investigating] (Tracking thread)

[Brian_Wood (Woadl)]

I’ve just stumbled onto this.
I also have a NUC 7i7 and have noticed my NUC’s fan has been going flat out which it never used too. I have 7 Sonos end points and yes if I reboot its very quiet but the second you play a Sonos device the fan screams. I have other none Sonos devices and they do not have this effect.
I have also noticed that from the last couple of updates I can no longer group Gen 1 and Gen 2 together it just says that Roon has lost control of the audio device

Hi @Peter_Loeffel,
Thank you for the additional data point and my apologies for the long response time. What you observed seems to confirm our suspicions that this was related to Sonos devices. I will merge this topic into the tracking thread that you linked to ensure you will get notified about updates. While I cannot give an exact timeline I want to assure you that an investigation is in progress. We appreciate how patient you’ve been with the process.

Hi all, similar problem here, I restarted many times my Roon server, streaming to a Symfonisk Table Lamp, but sooner or later CPU get stuck on about 50%.
I will disable native Sonos streaming, switching to Airplay 2.
Thank you all.
