Worth checking the System Setting Privacy & Security/Local Network/Sonos to make sure the Sonos App has access to devices on the local network. The app should ask for such access when started following the upgrade to Sequoia. Sonos does work with Sequoia:

Hi, thank you I did make the change and it works! 

I did as suggested and it worked fine after I uninstalled Sonos and then reinstalled it. Then, the next day, it was back to the same problem. So, I uninstalled again and reinstalled with a restart to get it to work again. The problem persists at this point.
