    Just want to ask a quick simple question.
    I just bought a new Macbook last week, and I noticed some crispy sound with the speaker.

    Here is the sound file.

    Is this normal?

    you can reproduce this by going to terminal and hold down arrow button with full volume

    CTRL+space → type terminal
    and hold press down arrow key for a few seconds
