Dell Inspiron Webcam Audio Issue

Hello. I have been trying to fix this for days now and I just do not know what to do. When I try to video chat or record a video using my Dell Inspiron 1525 integrated webcam there is a constant beeping noise. I understand that many people have had this issue as I have found questions relating to this on the internet but I can't seem to find a solution. Here is an example of someone having the same issue: YouTube - HELP PLZ. Annoying sound? (mine is louder). I can not hear it while recording a video but it's there upon playback. I've found that when I reduce the video size the beeping noise stops and the audio is great, but the video is too small. I've tried using a different mic and while the beeping stops, it is too low and you can not hear me. I've also stopped the fan to see if it was causing the noise but it's not the fan. I do not understand why this noise is occuring as it was not happening a week ago. I have not spilled anything on the laptop and everything seems to be working alright. This is all very frusturating. I would appreciate any advice you have, please lol. Thanks.
