Hi @pierre_jubinville — Brian is spot on for points the first two questions. Now for the crash:
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
What’s happening when Roon crashes? What kind of remote are you using? Is there any specific action that seems to lead to this?
