2018 MacBook Pro mouse and hiss

[thehumanplugin]

Hello,

I just bought a new 2018 MacBook Pro. When I turned it on, as it boots, I notice this low volume hiss and noise coming from the speakers. It also seems to be doing it when I load apps.

Is this normal? Do other people have this?

Can you guys try this? Start up the computer and listen closely to the speakers.

Thanks!
