However running DAC directly via Qobuz works fine.

This issue seems to have started after latest Roon update.

Does your Mac have the same issue if you disconnect the DAC Magic? Trying to isolate if this is a Roon Core issue or possibly a network issue. How is the Mac Mini connected to the network, direct Ethernet cable to the BT router or via WiFi? Also, are you running the lastest build of Roon, 923?
