Luigi, looking at front of volume pot (where knob attaches), Wiper is center terminal, CCW is counter clockwise terminal, CW is clock wise terminal.

Pin on pot ADC connector
Wiper PB4
CCW GND
CW 3.3V

So 3.3v attaches to terminal to CW or terminal to right of wiper looking at pot where volume knob attaches. GND to CCW or terminal to left of wiper. If you reverse GND and 3.3V, the pot will work backwards CCW would be full volume, CW would be no volume.

Just a FYI, how a pot works...
