You have to plug in the front panel audio connector into the HD Audio/AC97 port on the motherboard. Then configure it in the BIOS under input devices. Choose HD Audio over AC79 - the ASRock supports it
I'm currently using Turtle Beach PX21's, which uses a USB for the mic, and connects to the green audio connecter via the back of the computer. I want to use my computer speakers, which I need to plug into the green audio connector in the front of my computer. Will this work with my headset plugged in as well? I want to be able to use both whenever I want.
