Just like to say I have my HiFiBerry setup and running with Beta 1 Volumio.
I was using a HRT Streamer II USB DAC which annoyingly clicked and popped from time to time.
Now using the Hifi Berry and it works flawlessly!
Sounds amazing for the price and to be honest the HRT DAC sound quality is no better and it’s much more expensive
HifiBerry Works Great!!
