Hi @Damien_Sullivan ---- Thank you for the report and my apologies for the troubles here. As Daniel has mentioned, having a detailed description of the problem that you are experiencing along with the specifics of your setup will greatly aide in evaluating this behavior you are reporting. With this in mind may I very kindly ask you to please provide me with the following information:
-
A brief but accurate description of your current setup as seen here.
-
Please describe your network configuration/topology, as well as providing insight into any networking hardware you are implementing. I want to have a complete understanding of how your devices are communicating and what tools are being used to make those connections possible.
-
In regard to this issue you are experiencing:
“…but if I go into radio mode and a 16/44 Tidal track comes on it will play a few seconds then give me this message or just freeze entirely at the start.”
-
Can you verify what error message you are seeing?
-
Do you only have this issue while streaming TIDAL content or is this same behavior present when streaming content from your music collection as well?
The more detail you can provide, the better 
-Eric
