Users in the Apple Support Communities forum report problems with the audio volume fluctuating while playing videos on new 2013 13-inch MacBook Airs. The thread contains 85 replies over 6 pages at the time of this article.
The problem seems to be a system issue rather than app-related, being reported in iTunes, QuickTime, VLC, Hulu, Vevo and when watching web videos in both Safari and Chrome – but doesn’t seem to affect all videos. It has also been reported that the issue persists when running Mavericks …
Several users report that Apple seems very interested in getting their hands on machines experiencing the issue so it can identify what is causing the problem.

After being contacted by an AppleCare rep today, they do not yet have a fix. They are very interested in getting a hold of the affected hardware, and are willing to send a replacement immediately. However, they cannot guarantee it won’t have the same problem.
This is the second issue reported with the new MacBook Air, as widespread reports of Wi-Fi problems occurred in June.
We’ll keep you posted if and when Apple reports a fix or workaround for the volume issue.
