I am starting to get these popping and skipping sounds while listening to my music. I am using windows media player. I will be just sitting there listening to the song and then when i try to do anything at all, it makes this sort of light popping and slight skipping noise. It is subtle, but noticeable. It happens when i try to load a new web page, or open a new program. Basically if i want to not hear the noise, i can't do anything with the computer. I am using wireless headphones that i have had for about a month now, but up until this point i have not heard the sound. What could this be?
