Test on raspberry pi B+ without powered HUB.It work great just rarely click sound when press change song button.
But at first the sound volume is too low even i set volume at 100%.
i have to go to console and type "alsamixer" select sound blaster and set volume to full.
But i have some confusion How can it call bit perfect if it can set volume in alsa? and if i want to set it to bit perfect how much volume i should set in alsa?
thank you.
