Hi @Graham_Bird ----- Thank you for the report and sharing your observations with us. Both are very appreciated and sorry to hear of the troubles.
Moving forward, I would like to have our techs take a closer look into this by grabbing some logs from you. May I kindly ask you to please follow the instructions found here and send us over a set of your Roon logs.
Furthermore, can you please provide the details of your setup, as seen here so we have a better understanding of what you’re currently working with.
-Eric
