I was experiencing this issue today. My mic was really quiet, the person I was talking to couldn't hear a thing. I've checked the settings, put everything to the maximun (also in skype) and nothing happened, it was still quiet. Next thing, I googled that problem with hope, that I'll find something.I've found this site, so I tried some of the tips that were mentioned above. Since none of them fixed my problem, I tried something on my own. I own an Asus G750 notebook and I had Windows 8 preinstalled on it. When I plugged in my speakers or my headphones (Razer Kraken) the Realtek audio "whatsoever" always popped out and I had to choose some settings and stuff. It's important to mention that my mic was working good so I didn't have any idea what happened to it. I though that the cable got damaged or something, but since the headphones were working on my sister's notebook that couldn't be the issue. I was desperate so I tried to uninstall that Realtek "whatsoever" thing and guess what! Now it's working! Everything's fine. I'm sure there are different solutions for this problem. I hope this will help someone
