Headphone Conn=Combo
but Pincap is OUTPUT only so it cannot be retasked as Input

Does internal mic work or not ?

It Int Mic is correct and 0x06 [Audio Input] is used ,

ext mic may be at 0x0e

you can use hda_analyzer to switch the connection at node 0x6 from 0x0d to 0x0e
to test the external mic

There are also other possibilities 0xc and 0x12  if 0x05 is used
