volume fluctuation on macbook air

I have just purchased a new 2013 13" MacBook Air, and the volume seems to fluctuate by itself when I play back any videos. Does anybody know what causes this? Is there a fault with my Mac?

MacBook Air (13-inch Mid 2013), OS X Mountain Lion (10.8)

Random Volume Drops on the videos below.

@DJTaurus I believe, because so many people have this issue on original and replacement machines, that this is a software problem. I have seen countless cases of the replacements having the same issue. Hopefully if enough of us complain apple will come up with an update that solves this issue. If you want an air I would stick in there and wait for the update. Also be sure to call apple and let them know you are having this problem


EVERYONE CALL APPLE AND COMPLAIN SO THIS IS SEEN AS A LARGE ISSUE

I have a 5 day old MacBook Air 13" i7/8GB/256GB and I happened to chance upon this thread. Upon reading this, I went and test it out. I played 4 videos from Apple website: the "Designed By Apple in California", the "Making a difference one app at a time" and two TV ads on iPhone 5. I'm happy to report that there was no volume fluctuation. I'm happy to try out any YouTube videos you find with the issue. Let me have the URL.

Okay, I thought it was just me - maybe my new 13" MBA isn't adjusting the volume to as great a degree as others but I have noticed the sound going up and down on it's own, most often with web content videos. I was originally thinking it might have something to do with the microphones & the OS trying to adjust for ambient sound - but like it's lowering the volume when it hears loud sounds nearby for some reason. Then as it realizes it's quiet in the room the sound goes back to the correct volume.


Whatever the cause I'm one more "me too" to add to the thread.
