Hello! I am having a slight (bit very irritating) problem with my onboard audio hardware (Realtek ALC833). The 3.5mm microphone in jack causes some very strange sounding background noise. A 10 second recording of said noise can be heard here. I know some of the noise is picked up from my computer's rather loud fans and such, but the noise I am referring to is the odd screeching and and regular beeps. It is not caused by the microphone itself, as I have tried it with a USB audio device. Any explanations and/or solutions? By the way, I apologise if this is in the wrong forum. I was not sure whether I should post in the audio forum or computers.
