[Voyage-linux] Cubieboard 2 and MPD, (and NO external DAC)

[Joseph chu]

Hello Patrick,
What power supply you are using for the cubieboard2?
After I read your post, I tried my cubiebaord2 internal dac (with a switching mode psu) but the noise is too much that I can hear. But I will try a linear power supply later when I get it.
