Actually, most of the hda_intel sound codecs support jack sense to a certain extent. They are mainly used to mute/unmute speaker and microphone channels when headphones or external microphones are plugged in. Some of the codecs support additional sensing to determine the type of device plugged in, but that is very limited in the drivers, mainly because of the diverse nature of the systems that these codecs are used in.
