ProtoDAC TDA1387 X8 project

[DRONE7]

One of my Protodacs is fed by a Kali, one is fed from the output of a DIYinHK USB to i2c and another from an AK4137 resampler and none produce glitches.
I will try Pi direct and report.

An hour or two now Pi4 and ProtoDac via i2c MoOde 9.05 and no clicks or glitches. Tried with both Software and Fixed volume settings.

(Powering Pi and ProtoDac from Salas L-adapter so plenty of grunt there. 
When I first plugged the ProtoDac into the Pi4 using another Official Pi power supply it would not boot...greedy little ProtoDac   :-)
