    Microphone detection on Intel NUC


      I have an Intel NUC5i3RYK running Windows 10. It has a 4 pole audio socket, which can cleverly detect if the accessory is a headphone (ear only) or headset (ear and mic). Unfortunately this detection is based on DC current, and the microphone on my Plantronics headset takes so much current that the microphone is not recognised. I need to un-plug and re-plug in the microphone for it to be recognised. The microphone then works ok. But then when I re-boot the microphone is shown as not connected again.

      By experiment I have determined that the microphone must take less than 0.9mA for correct operation. How do I change this threshold, or better still disable automatic detection. I can not see anything useful in Windows or the BIOS.
