Can you please access your Device Settings>Device Setup>Advanced Settings on your sonos zone and confirm you have the proper format selected on the device? Roon will cater to the playback limits of the zone itself, so it could be that your sonos have been reset to a lower resolution playback by mistake.
If that’s looking good, next I’d safely stop your Roon Server from running, and then reboot both your server machine, sono devices, as well as your router, and see if the same issue persists.
I am just an end user like yourself who owns Sonos gear.
I would suggest to Reboot your Roon server and your Sonos kit.
This can sometimes happen and I have checked all mine and the 24 bit options are still there.
hello so i have power cycle both devices and unfortunately still the same issue no advance options in sonos connect format selection disapeared please help !!!
