Random popping and hissing sound

[Nightspirit]

I jus bought an Asus Vivobook Pro 16x OLED. (M7600) It works great except it makes a random pop and hissing sound. It doesn't happen often and usually when shutting down. Asus told me to send it for repair but I can't be without a laptop for long and can still return it to Amazon. Anyone know of a solution or if it's a major problem. Thank you.
