I encountered the same problem one year ago and even started a thread (http://club.cdfreaks.com/showthread.php?t=137187), but nobody replied . So I had to experiment and after an hour-two I found decision in that situation.
I connected MIC IN to MIC2 connector and GND to AGND connector (see pictures in my thread). MICPWR and +5VA left not connected. Thatâ€™s for microphone.
As for Speaker Port, all appeared even simpler. Two Spkout L go to Line out_L and BLINE_OUT_L, and two Spkout R go to Line out_R and BLINE_OUT_R. In such configuration everything works fine.
Now you have some other schema with line_in_r and line_in_l. A few weeks ago I saw some cheap JNC case with these connectors. And also didnâ€™t know where to connect them â€“ therefore front audio panel left unconnected. And I donâ€™t know the answer till now â€¦ :sad:
I donâ€™t understand why they are IN connectors, when the speaker port is OUT-port in its natureâ€¦.
That means that every manufacturer has its special and extraordinary view on standards :doh:
