This is the drawback of using dell-headset-multi which allow combo jack to support headphone, headset and microphone

You can try the patch in alsa devel mailing list archive for asus n750jk which support headset only

[Raymond (superquad-vortex2)]

As the codec cannot differentitate headphone, headset and microphone, you need to switch capture source to determine the jack type

it is just a simpifed dell-headset-multi by removing the support of headphone and microphone jack, assuming user only use headset

You only need to change pulseaudio to select headset mic when headphone jack is plugged

Add [Jack Headphone] to headset-mic.conf
