Macbook 2021 Speakers buzzing sound

Hello houmehrMKZ,

Welcome to Apple Support Communities. We understand that there are some sound issues with your internal MacBook speaker. Right?

Does this happen with headphones or only the internal speaker? That will help to isolate the issue a bit.

Try the steps in If the internal speakers on your Mac aren't working. If the same continues, test in another user account to see if isolated to your user account. The guidance from Set up users, guests, and groups on Mac can help set up a test account if you don't have another user account on your MacBook.

Take care.

The right speaker of my 16" M1 MacBook Pro stops buzzing when playing music when I am logged into a test user account. What are my next steps to determine how to stop the buzzing when I am logged into mynon-test user account?
