I have the ODROID C2 installed Rune Audio to feed the digital signal via I2S to the that it played perfectly.
But note that for this same DAC board I tried with RPi installed Rune but it played with no audio at all (I suppose the i2s signal from RPi is not suitable for ES9018K2M?!). In case you want to use RPi then you should use an external / boards to feed I2S that it played well as well (my friends did trial it ran perfectly). In case you use one of these boards, you could power it externally or from the power header (5VDC) on the ES9018K2M board.
