Fix Crackly Audio and Other MacBook Sound issues – Guide
The MacBook Pro laptops are expensive, but they offer exceptional performance, long battery life, and trouble-free performance as a result. However, this is not always the case. For example, many MacBook Pro users have complained that the speakers occasionally pop or hum and that the audio quality is poor. This occurs at low and high volume levels, but not with headphones. To solve this problem, many Mac users have turned to third-party software to improve their experience with their laptops.
How to Fix MacBook Pro Speakers Making Weird Noises
Roll back your macOS version
The latest macOS update has caused some users’ speakers to break, and it’s possible that there’s nothing wrong with their hardware after all. If that’s the case, you can try reverting to an earlier version of macOS and check if the audio issue is gone. If that’s the case, avoid updating your macOS version for a while. This should give Apple more time to fix the faulty code in the latest version of the operating system.
Create a new user account

In System Preferences, select the Users & Groups tab. In the left pane, select the Add User button. Enter your name and password in the fields. Click OK to add the new user.
You can now add a new lock to your account.
Select the account type, enter the details, create an account and run a test.
Use different audio or music software

Increase I/O buffer size to 1024

Some users said that changing the project’s sample rate to 48kHz and setting the speaker format to 48kHz worked for them. However, you may need to select the 48kHz option multiple times as the drop-down menu keeps flashing back to the default value.
