I have asus x570 prime pro mobo and its rear mic jack (pink) suddenly stopped working. Then when I touched the mic, it zapped me which means for some reason something was not grounded. After a while of checking connections I saw that my ups was leaking voltage in the ground terminal and so my PC was not properly grounded. I suspect that for this reason my rear mic port is not working. I've also plugged the mic in the front port and it worked. Also all the other audio ports are working as well. Can that grounding problem cause the rear port to stop working and if not then why its happening?
