Just got my Hifiberry Digi !
It was a little bit difficult to make it run
Just want to share my experience:
I thought I just have to enable I2c drivers in Web Ui as drivers for hifiberry now included in the last Volumio release. But it was not running.
After severals coffees and words that I cannot repeat here
Had to connect via SSH
sudo apt-get update
sudo apt-get install git-core
sudo apt-get install binutils
Had to edit /etc/modules and delete
to be like that
