What should the driver of Rune be set to?
Or did I miss something?...
These are the connections (pin's 12, 35 and 40):

Any of the GPIO 5v connections can be used for DAC power (VCC). For the DAC board pictured above
both ground connections on the DAC (GND) need to be connected to a GPIO GND. One of these DAC GND connections is actually a system clock input, it needs to be connected to ground to disable it. The DAC then automatically generates a system clock signal based on the BCK signal. So in cases where a PCM510x DAC has a system clock (SCK) connection pin, this needs to be connected to a GPIO GND.
Selecting 'Generic PMC510x' or 'HiFiBerry DAC' in the Settings UI work's fine, both use the same 'hifiberry-dac.dtbo' overlay.
