I know its not a faulty microphone because I have 2 of them and they both do this! the "line in" also does this too ~.~
When I go to "control panel>recording>microphone>levels" its shows my microphone with 0 volume and muted. If I were to change the volume to 100 and unmute it, after around 1-30 seconds, it becomes muted again with 0 volume!
