Many times, my rMBP makes some kind of sound signal. I don't know how to describe it, but it should be there to signifying something. It comes just out of nowhere.

Do you know what sound I'm talking about? Do you know what is it for?

If this is really coming from the speakers it may be a 3rd party sound for something, but not a OS X system sound afaik

Yes, it's definitely coming out of speakers. I haven't determined yet what it should be. Probably some kind of notification from any other app.

I just found out that this sound appears every time when I open Messages. Same to you?
