Hello, how to properly connect the 13-pin orange Audio plug from LENOVO M72E to the standard 9-pin HD Audio (black) so that it correctly detects devices in the headphone and microphone jack. The 13-pin orange plug has 9 wires, it should fit the standard 9-pin HD Audio, but the connection...

there is no m72e but it should fit...

Can you check if I`m doing it right? 1 to 8 - Jack presence signal send 3 to 9 - Line out jack presence return 5 to 5 - Mic in jack presence return 6 to 2 - Mic in bias / left 8 to 4 - Mic in signal / right 9 to 3 - Front panel presence return 10 to 10 - Line out left 12 to 6 - Line out right 14 to 1 - Ground

Thank you darok for your help. Topic to be closed.

Hello, how to properly connect the 13-pin orange Audio plug from LENOVO M72E to the standard 9-pin HD Audio (black) so that it correctly detects devices in the headphone and microphone jack. The 13-pin orange plug has 9 wires, it should fit the standard 9-pin HD Audio, but the connection descriptions differ. I would like to ask for clarification of all knowledge on this subject. Best wishes.
