I am in the process of rigging some old AC97 jacks or work with HDaudio (the jacks are behind a glued on face plate, so I'm not gonna swap them)
The pinout for HD audio has Sense_send and mic/headphone detect pins
so jumping sense send to a detect pin enables the jack
i also found out that pulling just a few thousandths of a miliamp from sense send causes very odd behavior like the ports enabling/disabling at random even with the detect pins being in a NC state
now i am wondering what this sense_send pin really is clearly it can't just be a 1.8v power rail as i though it was
