I finally managed to acomplish a similar setup: RP2+7inchTouchscreen+DigiberryDAC+
Problem is that although MPD is working and also the Spotify plug in from within Runeaudio works great, I have no sound at all with Spotify Connect.
But I''m happy that it autostarts when booting, took me a while

Any hints on this? Also when not using DigiberryDAC+ I have no luck so far.
