Connect a line source to the line input and check if it records.
Alternatively, use an electret mic with a pre-amplifier to bring it to line level.

something tells me the jack for the head set which most likely has the mic ring on it isn't set well any more. Maybe cracked on the board or stuck disconnect pin?
