[1] Set headphone amplifier in Power-down mode before setting audio DAC in Power-down mode because the line output is connected to
the headphone driver the output of the headphone clips towards its analog supply.
[2] Exclusive the input load of the headphone driver which is 10 kΩ.
[3] The output of the DAC is already connected with the headphone driver which has an input load of 10 kΩ.
