a single jack headphones with a mic (mic doesn't work)

Just because it has only a single jack doesn't mean it is an input/output one. Did you check that first?

Also, sadly some devices don't have the greatest dual ones leaving it so that only some headsets work in them, and not others. The simplest fix, if that is the case here, is to get a 3.5mm to USB adapter and connect that way. (which works if the jack is only output as well) Luckily they are quite cheap.
