The subject HP notebook has apparently incorporates a TRRS connector for audio; combining L&R audio out and microphone in. What is not specified in the user manual is the pinout of this connector. There are two known versions of this 4-pin connector:
Version 1: Tip-Left, Ring1-Right, Ring2-Gnd, Sleeve-Mic.
Version 2: Tip-Left, Ring1-Right, Ring2-Mic, Sleeve-Gnd.
Can someone tell me which one of these pinouts the HP Pavillion 17 Product E8B94UA#ABA uses?
