I have earbuds with an in line mic on it. They are some regular headphones with a mic. They have a 3.5mm plug on the end. I have Windows 7 and a 3.5mm jack on the laptop. I connect the headphones and talk on Skype. The problem is, I get audio through the headphones, but my mic on the headphones isn't the mic being used to record sound. Instead, it uses my built in laptop mic. I don't want this. How do I get my headphone mic to work as my default mic? Thank you in advance.
