I have setup a NUC i7 with 8 GB RAM and a 246GB SSD (also has a 1TB HDD). I connected it directly to my router as advised so it is not in the same room as my audio system. I can load the remote on my old pc connected to my audio system and TV it is asking for audio output but is only showing interfaces connected to the Rock Core. It doesn’t see my DAC. Which was my output device when my core was on the PC. How do I see the DAC now?
