I want to use a 4-pole 3.5mm jack as if it were a mic-and-headset combo in order to hardware-disconnect the microphone in a laptop computer when it's not required.
So: when you plug in an ordinary mic-and-headset combo, is it detected by hardware or software?
And when you mute the mic with the little mute button in the cord, does it make the mic open circuit or short circuit?
Sorry there's no mention of Brexit in my question: I'll try and do better next time!
Thanks,
Nick
