The digi plays very nicely, however, on starting playback of audio files it emits a very loud pop / click sound through the speakers.
I'd appreciate any help to eliminate that
What is use is a Transcend 1T hard disk connected by usb to a raspberry pi 3 and a digi+ card. Power supply is a standard rb pi 2.5A wall wart. The output is through the toslink out to a DAC. The issue is the same with two different amplifiers.
