Barracuda X no audio when mic attached

ive been googling for a while and can't find this issue. my new barracuda x works perfectly...as headphones only. if i plug the mic in, total silence. the mic also doesnt work at all. it is visible to the computer, set it as my input, and it even registers a bit when i plug it in but not when i make noise into it. EDIT: so it was in the wrong hole. shrugs. i was trying both the whole time so I did my best. I'm still putting the answer here because I'm surprised it's not a more common problem, what with the instructions simply saying "plug it in." well here's more instructions for those who need it: it goes in the uppermost hole and it only goes in one way so you may need to rotate it.
