I received my hifiberry digi. I soldered the p5 header on my raspberry pi. Installed Volumio 1.3 Beta. This has a explicit option for the DIGI card. USB stick with some MP3 files. Used the optical out to my DAC and the music sounds wonderfull. I'm very pleased.
(I had some troubles using Volumio 1.2 , optical out not working, but i solved it using 1.3beta. )
Looking forward for a great week-end, thanks you guys....
Minor Question: can i adjust the volume using Volumio? Stays at 100 in my case, i have to use the dialer on my amp.
