Sadly I didn't find the solutions here helpful for my particular situation. I have an windows 8 laptop and I thought my headset would have its own microphone icon added somewhere in sound when I plugged it in. I had a Real tech audio issue, where my laptop thought I plugged in a headphone instead of a headset.
The solution: Go to Real tech high definition Audio Manager in control panel when you click on hardware and sound, should be the last option, then click the top right yellow folder, and it should say enable pop up dialogue when device is plugged in or it will show you a "disable front panel jack detection" then you will have to enable. Works perfectly and hope this helps for anyone who had the same problem. I had a video link but this site told me in French to check my grammar in red ink loll. I can't even use the right loll or use the shortened high definition word so I hope I was able to help someone who has the same situation that I did.
