Hi Dan, thanks again in helping me get thru this installation. However, after completing all the steps using the monitor and keyboard, I couldn’t get any music to play using the Roon Remote app on my Galaxytab 4 tablet. All my music files are present on the app and the metadata is beautiful. On the app, I went to “Settings” and “Enabled” my Meridian Explorer 2 DAC, the input of which is connected to my Rasberry Pi 3 USB port. The output of the DAC is connected to my Shanling headphone amp. What else must I configure to get the Rasberry Pi to play my files?
