Hi there. Last night i decided to use my mic on my 8204 for the first time only to find that it loops back any audio output back into the mic. So for instance if there is a song playing in windows but iv got headphones plugged in so that it cant be feeding back I still find that the mic picks up the song perfectly almost as if the software is feeding the audio output directly into the audio input. Has anyone else had this sort of problem? Is there a fix?
