I am using a Raspberry-Pi 3 with the HifiBerry DAC+ Pro as a Network Audio adapter (audio renderer). The music files are first read and processed by HQ Player Desktop in a Mac and then transfered by Ethernet to a networkaudiodaemon on the Pi which in turn feeds the DAC+. The sound is glorious.
I have used the HifiBerry installer and my current OS is the Jessie Lite and now wish to to prevent some features from starting up and running like Audio (mini-jack) out, USB, HDMI and Video.
I was hoping that I could get some help on this for I am a command line ignorant...
