Problems with Core Infinity

[Dannythered]

Many thanks, I'll give that a go

No joy, still same issue, strangely the new IP addresses I set up didn't show up in Roon, just the original ones, did I do something wrong? Also tidal disappeared as did my Roon account, couldn't connect to either

What device are you using for a router? In the router you can specify assignment of static IP addresses to devices such as your Mac Mini and your Devialet. Based on that setup you then configure the Mac Mini and Devialet accordingly.

Let us know what router you are using and we might be able to help.

Many thanks for the kind offer, my Mac mini running Roon core and 2 Pros are connected to a Netgear GS308 8 port gigabit switch which I believe is unmanaged, this is in turn is connected to a Cisco router which in turn is connected to my broadband router, I run all my music on a separate network from the rest of the house. I have a submitted a request to Devialet but no answer/support in over 48 hours.
