I use a headset for a voice recognition program on my PC. The cable on the headset splits into two input pieces: a black one for the headset and a green one for the microphone.
Now, my computer has two slots where I can plug these into: two at the front and two at the back. At first I tried to plug them in at the front, but it would only let me here through the headset and not use the microphone. I can plugging in at the back and it works perfectly, but it is more of a hassle to plug them in back there.
Does anyone have any idea why my front two input jacks won't recognize my microphone?
