After weeks of trouble-free operation, I have been experiencing increasing problems with the volume control of my SONOS speaker group (Arc, Sub, 2xPlay:1) via the native R2 SONOS integration, although I have not made any changes to the settings (firmware 1.6.10 since release).
These can then only be resolved by an R2 reboot. In the meantime, I have now switched to SONOS volume control via the Home Assistant SONOS integration and this works without any problems.
Am I the only one affected, or do other R2 SONOS users also have this problem?
