@Gaspar74 just stack the Hifiberry Digi+ Pro or Digi2 Pro on the Pi and stack the Protodac on that 40 pins GPIO header (sandwich of 3).
Select as audio card the Hifiberry Digi Pro. Make sure you just playback 16bits and don't forget to inverse the audio.
@DRONE7 concerning the Digi2 Pro; that is about the separate I2S header, no need with the Protodac it is directly connected to the 40 pins GPIO header. And if you need the I2S signals for an external DAC (which doesn't have the Pi GPIO header) you can just breakout this signals from the 40 pins GPIO header.
