I just assembled a Pi 3 with a HiFiBerry Digi+ and metal Digi+ case and flashed a new SD card with runeaudio 0.3beta. I can't detect the Pi on the network using Fing and cannot connect at runeaudio.local. I can see a green LED on the Digi+ and a red LED on the Pi, but no flashing LEDs are visible, but it's virtually impossible to see inside the metal case. If I take it away and put my old Pi and Digi in its place it all works OK.
Any insight or advice?
