The pcDuino V3 Nano has a 3.5mm TRRS jack socket for audio, using the CTIA standard pinout, connected to HPOUTL, HPOUTR, HPCOM/HPCOMFB and MICIN1/VMIC (via appropriate RC networks) on the A20. The PH00 GPIO is wired for headphone plug detection: it reads 0 when nothing's plugged in, and 1 when a plug is inserted. LINEINL/R and FMINL/R are not connected.
