Hey so i just got my Audio Technica M20x headphones and it seems that my mother board the Asrock Z97M pro 4 the jack on the back which there is a black one assuming thats its the Hd audio thingy that it has and i really have no idea how to bloody fix it i plug it in i change the default playback and nothing i connected to the front of the pc and i really dont like having it there . HELP PLS i dunno whats happening .-.
Green plug - Front Stereo (The one you use for 2 channel devices)
Blue Plug - Mic
Black plug - Rear Stereo (Needed in conjunction with green for quadrophonic playback or in conjunction with green, yellow/ orange for 5.1 also with pink for 7.1)
yellow/orange plug - Center speaker and Sub
pink - middle stereo (required for 7.1)
So I would suggest taking it out of the black port and put it into the green.
