I am using PI 3 with HiFIBerry DAC+ Pro. I have gone through some posts and I got a bit confused. Can you please address some basic questions.
First, does the HiFiBerry driver automatically configures PI as slave and DAC+ Pro as Master?
I played some wav files using aplay command from PI. Does that not mean that PI is a master and DAC+ Pro a slave because audio is written to DAC+ Pro?
