Mine does this when I have a CD/DVD in the optical drive. I just figured it was reading the disk and not giving full attention to playing the sound properly. Doesn't hurt anything.

My macbook does it when my external hard drive is plugged in. As soon as the drive has spun up and is fully turned on, the macbook sound stops repeating and carries on like normal.
