Roon is working great and plays through all systems except a ‘McIntosh MX123 Processor’ (main system). Previously worked with same equipment but after a reformatting the PC, it wouldn’t connect again. I believe my settings are now wrong.
More info on your setup would be helpful.
Could you add more details on the PC setup the Roon Server running on.
How is the Roon server connected to the McIntosh MX123?
The computer is a Geekom GT12 Pro Mini PC running on Linux OS. It is much faster than the Roon Nucleus Plus hardware which I once had until it failed. The Ethernet comes directly from the modem. The computer is connected to the McIntosh MX123 by an HDMI cable.
