I'm building a computer and I have these skullcandy headphones, which is used for iphones and cell pohnes. Its one jack but it works as mic and sound out. Is there any sound card with such a thing?
I don't know of any sound cards with such output and I don't think it would make sense because there's usually stereo out/in which is 2 channels x 2 + ground = 5.
But there are adapters that split off into a headphone and mic jack.
Search for trrs jack to 2x trs plug.
