When I wake my MacBook Pro from sleeping, once the wi-fi has connected, a sound is played through the speakers.  It's not a sound I can find in my Mac's library, nor can I pinpoint which program is making it, as I've tried closing each one before putting the computer to sleep.


Here's a YouTube clip of the noise:  http://www.youtube.com/watch?v=QOZ-Xo8N1oI


I could've sworn I heard my Nexus 7 make the same noise one time, but I think it's just down to this sound driving me nuts!

MacBook Pro, OS X Mountain Lion (10.8.2)

    I am not 100% sure what application is making the sound (first guess is Finder, second is Messages) but I am pretty sure that noise is made when your computer connects to the network. I do not know how to turn it off, but maybe this information will help you track down a solution. Please let us know if you are able to turn off the network connection sound.

    Yes, it's definitely a network thing, as when the wi-fi is turned off, no sound is heard.


    It must be some sort of background service that requires access to the internet, as I have tried each common application one by one, opening it, putting the computer to sleep, then waking it again.  As I type, I can't get the sound to play any more.  'Messages' is running, according to the Activity Monitor, so I don't think it's that.


    I guess I'll have to take a snapshot of what processes are running now, and again once the sound decides to play again!

    It turns out it is 'Messages', I fired it up just now and it played the noise.  It's not an application I normally use, hence me disregarding it.  Thanks for your help though!
