Is it possible to find out if anything is connected to the headphone port?

Answer 1

On linux systems, see /proc/asound/card0/codec#number , there are nodes in it and they have a Pin-ctls field, so you can determine whether something is connected or not by the value in it. There are also many variations in the form of libraries. There is an api
in windows Pro smartphones above answered.

Mozho, if such a possibility is provided in the equipment and there is an implementation in the driver.
see the technical description on the soundtrack. although maybe these details are marked chipboard :)
