Fix Crackly Audio and Other MacBook Sound issues – Guide
MacBook Pro laptops They are priced high, but consumers can anticipate exceptional performance, long battery life, and trouble-free performance as a result. However, this is not always the case. Unfortunately, Macs, particularly Pros, are not without their flaws. 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. Let’s take a deeper look at what’s creating the problem and how to solve.
How to Fix MacBook Pro Speakers Making Weird Noises
Roll back your macOS version
Has the latest macOS update broken your speakers? Maybe there’s nothing wrong with your hardware after all. 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
Check if the audio issue is isolated to your account or if it is a system-wide issue. Test on a similar account. In others words, if you are having this issue on an admin account, create a new admin account, play a song and check the results.

Check if this issue is isolated to a specific audio or music production program. For example, if you primarily use GarageBand, check to see if cracking, popping, and pulsating sounds occur in other tools. Test Dorico, FL Studio, Sibelius, Logic Pro and other digital audio workstations and see if you notice any difference. The software may be incompatible with your current version of macOS.
Increase I/O buffer size to 1024

Boot into macOS recovery
