I'm using a pair of simple headphones connected to the audio jack of my Hp 2000 laptop running ubuntu 13.10. I've been having trouble with my headphones ever since I got them. Today, they just gave me a lot of static all day to the point of being unusable. After reading a few webpages on this and trying to clean out the headphone jack with some isopropol alchol, they still gave me static. I tried testing them in sound settings. I heard front left and front right clearly and crisply and was stunned. What could have caused this? Is it some sort of interference from my microphone. That would be strange considering I have my mic on unamplified 100% - OFF.
