Pop sound between tracks with IQaudIO Pi-AMP+

Just installed Volumio on a new Raspberry Pi 3, with an IQaudIO Pi-AMP+. With every song I hear a not too loud but obvious ‘pop’ sound when starting a new track. This is annoying. Does anyone have a solution to prevent this?

People have it over here as well:

I think it’s related to Volumio re-starting or initialising the DAC before every track. Seems easy to solve, but how?

Turns out, it was a faulty board. The DAC replacement solved it!
