    For the past couple of months my MBP has been emitting loud beeps from the speakers:

    1) It beeps SUDDENLY
    2) Lasts between 2 - 10 sec
    3) After which my MBP volume generally goes down by 50%

    The beeps are reminisce of old PCs when you press a key too much and the comp hangs, or I think it is the same kind of beep for some start-up troubleshoot methods on MBP.

    Anyone has had similar experience or knows why this is happening?

    Me too - EXACT same loud beep issue.

    I JUST had this happen to me too. I've been searching around the internet (and these forums) and have come to the conclusion that this is a RAM issue. I found this thread: http://forums.macrumors.com/showthread.php?t=622245&highlight=loud+beep+from+macbook

    And in particular a post by mkrishnan saying this:

    - Bad memory module (which would need to be replaced)
    - Bad memory slot (logic board would need to be replaced)
    - Badly seated memory module (you can actually check this yourself, if you're comfortable doing it).

    This actually makes sense for my situation because I was using Garageband and playing back my audio when I got the warning saying that playback could not happen because of lack of memory (which shouldn' be a problem for me because I run everything in the CS4 Master Collection with no problem. So I'm going to check that my RAM is seated properly (it's OWC ram).

    I hope that ends up being the problem because I don't know how I would decipher between the first two possibilities by myself (aka by NOT going to genius bar).

    I will report back...

    So I cracked open my MBP and decided to take a look at the memory modules. Neither looked any different from before and they appeared to be seated properly. Nonetheless, I removed both and just swapped their places.

    When I booted back up, my volume had come back to normal.

    When I opened Garageband and began to play the audio back, it appears to be normal again.

    Still perplexed and I don't think I fixed anything. We shall see.

    Come to think of it, my Powerbook G4 did the exact same thing when the memory slot was dying.
