i had speaker system that was to close to my computer another time it was my ceiling fan gone bad made my sound in my computer heard cracking noises. it can be from many thing even a mic on the computer running disconnect see if the noises go away, could be bad wiring speaker connection or mic plug-in, or even web-cam gone bad too

when i use computer sound connection to tv set and open say Firefox i get a loud buzzing sound, less after i close out firefox, same for other browsers too sadly. have to turn down the sound on tv-set the buzzing noises fade away some
