I have no luck, there is no sound out.
Setup: Samsung Galaxy Note II phone, with OTG (on the go) USB cable. The power shouldn't be a problem, because the $10 USB cable I bought connects 3 things together: usb charger, phone and DF. The USB wall charger provides extra power to the DF.
Result: DF turns pink, which is not too bad. Note II seems detected something, because when playing music Note II's internal speaker silent.
But DF is also silent.
I guess android doesn't have driver for this kind of usb audio device. Maybe wait for 4.2.2 and see.
