Hi everyone,
We’ve received numerous reports that updating to the most recent Sonos firmware (15.3) has restored connectivity via the Sonos network in Roon on both S1 and S2 series endpoints. We’ve tested and confirmed in-house that updating Sonos firmware will resolve the error and restore playback.
For those of you experiencing this issue, please update your Sonos firmware and report here if you continue to experience any issues. The team will mark this post as a solution and keep the thread open for several days to investigate any continued reports of playback failure matching the symptoms.
Thank you again for your patience.
