Strange sound problem

[blaraka]

Hi,
I've got really strange sound problem. After installing Mountain Lion I hear strange 'puff' sounds from Probook speakers from time to time. There are two types of those, one has higher pitch. Does anyone know what it might be?

EDIT:
I guess those might be just really stupid Messages sounds ;d

I have the same problem! have you found any solution or at least where it comes from?

As I eventually pointed out in the post above those were Messages app sound for my friends logging in Gtalk and logging out of it
