Macbook pro 2019 making weird sound from the speaker when starting up

[dzamm]

Hi, my Mac is making this strange noice from the speakers when a start it up (i attached the sound). Im not sure what can cause this, it does only come from the speaker so i dont think its a hardware problem. Does anyone know what could cause this? Maybe some program on the computer?

Note: It does not happen every time i start it but most almost every time.

Model: MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports, MacOS Big Sur

I don't have an answer for you, but when I played your video I thought, wow it sounds just like a woodpecker, how odd! Then I realized my volume was off and it was, in fact, a woodpecker out my window. Oops!

Hi! apart from the sound, have you noticed any other odities while booting or working with the mac? Have you tried some troubleshooting of your own?
