I have literally the same issue. I have the roon nucleus plus along with many zones for my audio. I have the new sonos amps and ports throughout my home. They tend to stutter after trying to group 4 or more when I group them within the roon application.
Hello @Mike_Goff ,
Welcome to the forum and apologies for the delay! Our team’s queue is longer than typical at the moment, but we’re working to get back to everyone as quickly as we can.
Can you please share a screenshot of your Signal Path when you have these zones grouped and playing?
