Describe your network setup
Silent angel M1 and a switch from my internet provider
Welcome to the forum and thanks for reaching out. Is this a new issue, did the M1 previously work or has it not worked at all so far? Sometimes devices need to be placed into Roon Ready mode, are you by any chance able to access a web configuration for the M1 and check to see if you have this option? Have you reached out to Silent Angel regarding this issue yet?
