my PC's front panel has Mic and Line Out sockets which I've connected to my motherboard (ASUS M4A78LT-M LE AMD 760G) using 10-1 Pin cable provided. The problem is that when I connect microphone it doesn't work. Headphones seem to work fine but my audio mixer software doesn't show anything connected. When i connect mic and headphones in the back panel it shows straight away in the software that something is connected. Is there any option I should switch ON or OFF in Bios or maybe some kind of jumper on the motherboard needs tobe adjusted to fix this?
