Today, out of nowhere my windows movie maker 2.6 started to f*ck up my sound BUT, I decided to record a video with camtasia (to record my desktop) to show you how is the sound in the .avi file (good) and then in the .wmv file (BAD).
So... okey, I recorded it, while I was doing so the audio was exactly as planned, the .avi was perfect while the .wmv had some weird buzzing sound.
THEN, I was watching the final video recorded by camtasia and. WTF BOTH FILES HAD THE SAME WEIRD SOUND like BZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ. Both of them. WAIT, im not done.
Then, I decided to upload the video to my youtube account so i can show you. AND WTF IS HAPPENING BOTH FILES HAVE THEIR AUDIO FIXED.
Just look at this (it's a 26 secs video)

The first file that I open in fullscreen should have the audio just like that, with good quality, no background sound, etc.
BUT THE SECOND ONE, should have something like a BZZZZZZZZZZZZZZZZZZZZZZZZ sound in the background that I can even hear right now while playing the video (the one that you just saw) in my desktop.
Edit: in case you were wondering, my audio is fine as always, it's not like I hear that BZZZZZ in any other sound file like .mp3 or idk, some random video.
Can anyone explain me wtf is happening here? my face looks like this
