Is it coming from the speakers or is it from inside the MacBook? PowerBooks and MBPs make a sound that I suppose sounds a bit like the trash rustle when they are opened. It's the optical drive checking to see if there's a disc present...I presume MacBooks make a similar sound. Could this be it?
Aha! Found what I was looking for. Woohoo for searching! 😀
For me, I get the optical drive noise which I consider normal (so no problem there) and then the fans kick on. The thing I'm posting about is the strange "woosh" noise a few seconds after the screen turns on. It sounds sorta like a drum roll, a "woosh", or a slurping noise, and it goes away after 2-3 seconds or so.. It goes when the speakers are muted/unmuted and when it's plugged/unplugged. It doesn't bother me (it actually sounds kinda cool), but I was just curious as to why it does that.
yea that noise is kinda hard to describe... i get it too
I get the sound too sometimes waking my MB from sleep. It's kind of sounds like static or something like that...
I don't care, as long as nothing is wrong. Would be nice to know why it makes the sound though-
It isnt a big deal, but I have it too, I notice it quite often, it is very strange. not sure how to describe it...
