WebJul 7, 2024 · PWM audio can also be used on GPIOs 18 and 19, so add the pins_18_19 parameter to select that location. pins_12_13 explicitly chooses GPIOs 12 and 13, although this is the default behaviour so is there only for completeness. WebThe original Raspberry Pi used an RCA connector, and a standard RCA composite video lead will work. Other models (Raspberry Pi B+ and later) combine the audio and composite out onto the same 3.5mm jack. This requires a particular type of lead, with audio left on the tip, audio right on ring 1, ground on ring 2, and video on the sleeve.
