I have the Raspberry B model and I know that its working with xbmc but not with volumio.
I can boot it, takes about 7 min. I can se that my keyboard is working but after the 7 min. everythings freezes and the keyboard is not working any longer.
I can’t access it via volumio.local/ with chrome for mac os x. I have tried to burn the image to the sd-card on my mac and on a win8 pc with the same result.
Same here. I had a power source which allowed me to listen for 5-7 minutes, then it just went down. If you have B+ (not sure about Pi2) you will see the red light on board to flash when power is low, that is the best indication. Mine flashed a lot, with new power source it is steady.
