Here is the guide to installing headless PlexAmp on a Raspberry pi: PlexAmp-installer for Raspberry Pi with armv7l HW

It incorporates the setup for the Hifiberry or a clone.

For the allo digione:
Add the config. to /boot/config.txt
dtoverlay=allo-digione

You may also want to comment out the dtparam=audio=on line in the config.txt to disable the “internal soundcard” of the Raspberry.
#dtparam=audio=on

Hope it helps!
