Hi @KJ21, welcome to the Sonos Community!
I’ve had a look into our internal information and there was an issue where the Control4 integration was broken on the newest Sonos firmware, however this issue is marked as resolved. It’s recommended you have the latest Sonos player firmware and that your Sonos app is up to date. Control4 is releasing a fix through a staged rollout process which should be automatically implemented, so no update to the Control4 system is needed on your end.
If you’re still having issues after making sure everything is on the latest version, then please contact our support team for further assistance. They have the tools available to look into your system and troubleshoot this issue.
