I do not own a Holo May DAC, but a very good friend of mine does. As I understand it, is that the PLL on the Holo May can conflict with I2S. I suggest turning PLL off when attempting to work with I2S. My friend decided this was too much of a PITA, as his principal source is a Lumin U1 via USB. He has a Shanling CD transport which is I2S capable, but finds it easier to just use digital Coax.
