The MacBook Pro scratching sound is one of the most common MacBook issues, and it can negatively affect your listening experience. This problem can stem from one of many reasons, and fixing it as soon as possible is crucial if you want to maintain an excellent listening experience.
While the issue is complex to solve, you thankfully have multiple possible solutions. Today, we’ll show you how to fix the crackling sound on MacBook Pro and stop MacBook Pro audio popping. To ensure that the problem doesn’t reoccur, you’ll also discover the top reasons why this happens in the first place.
The MacBook Pro speaker buzzing problem can stem from multiple causes. Some problems are hardware-related, whereas others are a result of software issues. You’ll find the top reasons below:
Outdated software is one of the most common reasons why you’ll have problems with MacBook Pro clicking noise from speakers. As your software becomes older, your device needs to work overtime to perform basic functions. So, it’s vital that you always keep your macOS up-to-date.
If you’ve changed your MacBook Pro audio settings, you may encounter errors that stop the sound from coming out as it should. For example, changing the sound input may result in fuzzy noise from your headphones or speakers.
You can play sample rates up to 96 kHz on your Mac. But while this works for files that have the capacity to play audio at higher sample rates, it’s not always the case. You need to consider the types of audio you usually listen to and adjust your settings accordingly.
The MacBook Pro scratching sound is sometimes caused by damaged speaker surrounds rather than software-related problems. If external debris or liquid has gotten into your speakers, that could potentially stop your audio from playing as it normally should.
Sometimes, your audio doesn’t sound as it should on a Mac because of conflicting sound effects. For example, some files might have old film-like noises. These can make it appear like your audio sound is crackling, even though that’s the intended effect.
Luckily, it can be easy to fix most sound not working on MacBook problems yourself. Whether your speaker is crackling at high volumes, you’re hearing random clicking or popping sounds, or any other audio-related problem, our guide will take you step-by-step through numerous tried-and-tested solutions:
The easiest place to start is by lowering your MacBook volume. On your MacBook Pro touchbar, do the following:
If you tried turning down the volume on your Mac, but the issue prevails, reset your device as a next step. Follow these instructions to do that:
Sometimes, issues with your MacBook Pro speakers crackling are app-specific. To ensure that the problem doesn’t impact your entire device, open different programs and play sounds. For example, you can experiment with Safari, Spotify, and audio or video editing software. Simply choose a file, song, or video and tap the Play button.
You should also make sure that nothing is blocking your speakers and stopping them from playing audio at their maximum capabilities. To clean the surface, use something like a toothbrush or microfiber cloth. Our advice is to ensure that bits don’t end up in your speakers, and DON’T use liquid—if you do, you could damage your speakers beyond repair.
You can also try using a compressed air can, which you can purchase from many homeware stores. It’s also possible to order compressed air online.
Too many processes running at the same time can stop your MacBook Pro from running its hardware efficiently. Therefore, your speakers may also not operate as they should.
You have two options for closing unnecessary processes:
To quit an unnecessary app:
To close processes via Activity Monitor instead, follow these instructions:
Your Mac will make sounds upon starting up, receiving notifications, and in several other circumstances. You can turn off these sound effects to make sure that you only use your speakers for essential sounds, which could help preserve them. Follow these instructions to do that:
If you feel like your current audio sample rate is hindering your Mac’s ability to perform properly, you can change it via Audio MIDI Setup. Here’s how:
Core Audio handles all of your MacBook Pro’s audio settings, but it can also result in your speakers crackling. So, you should try turning off Core Audio if you still can’t use your device properly:
A crackling sound from your speakers could be the work of a built-in sound effect. To check your sound settings:
Your audio speakers crackling could be a result of your MacBook Pro heating up. Your device may get hot because you’re using it outside in warm weather, but it could also have something to do with you running too many processes at the same time. Either way, the best thing you can do is let your device cool down:
A common reason for your MacBook speaker to sound like it’s crackling is that you haven’t installed all the available software updates.
To update macOS on your device:
Another potential way to stop your MacBook Pro speakers from crackling is to use software that will automatically fix the problem for you. MacKeeper’s Find & Fix tool is one such program capable of doing this for you.
Here are the steps to utilize our Find & Fix tool effectively:
MacBook Pro speakers crackling could very well be a hardware issue. To check this, try running Apple Diagnostics—a feature built into most Macs used to check your device for any hardware issues. This can be a complicated process, but we’ll talk you through it step by step:
Let’s go to the instructions now.
The process is different for running Apple Diagnostics on Macs with an Apple Silicon chip. If your device falls into that category, continue with the following steps:
For Intel-based MacBooks, the process to run Apple Diagnostics has several more steps:
Alternatively, distorted audio could be related to an issue in the NVRAM. The NVRAM stores particular settings such as time zone, sound volume, and display resolution, regardless of the power being turned on or off. A quick(ish) fix for this could be to reset the NVRAM using the following steps (on Intel-based Macs):
If you own an M1 Mac, resetting NVRAM will be a different process, as M1-based Macs don’t support NVRAM. Try this alternative way:
Because NVRAM is used to store settings such as time zone, sound volume, and display resolution, you may need to go to system preferences and adjust any settings that may have been reset.
Also, you can try resetting the system management controller (SMC) by following these instructions.
Important note: You can’t reset the SMC on an Apple Silicon Mac.
Safe Mode is a feature available to macOS users that can help you determine whether a problem is being caused by the software when your Mac starts up.
First, determine whether your Mac runs with Apple Silicon or an Intel Processor. You can find this out with the About this Mac feature. A Mac that runs with Apple Silicone will have an item labeled chip and the name of the chip used for your system. A Mac with an Intel Processor will instead mention a processor, such as the one pictured below.
After that, you’re ready to restart a Mac in a safe mode, based on the type of your processor:
Safe Mode should work to clear your Mac of any problematic software and unnecessary cache, leaving your Mac working faster, and smoother. To boot into safe mode on an M1 Mac, follow these instructions:
Hopefully, Safe Mode will eliminate any potential startup problems your Mac may have been experiencing. If your Mac has an Intel processor, you’ll instead need to follow these steps.
Performing a PRAM reset on your Mac is good for solving issues related to corrupted hardware on your device. So, it’s well worth trying if you’re still having issues with your MacBook Pro speakers.
If you have a MacBook Pro with an Apple Silicon chip, you only need to turn your Mac off and on again. Your PRAM will then reset.
For Intel chip users, follow these steps:
Depending on your device, you’ll notice different prompts for when you can let go of the keys above. On an Apple T2 security chip Mac, wait for the Apple logo to appear and disappear twice. If you use an older device, listen for two chimes before letting go.
