I'm using the DF Mini Pro mp3 player SKU DFR0768 as a stand alone unit and having difficulty with getting the volume control to work. I've tried connecting 33k and 56k ohm resistors in line with a push button between ground and KEY (I couldn't get a 51k resistor as specified), but there's no effect. Any ideas out there ?
