The sound card, in general, is a component of a computer that plays sound. It converts analog signals from various sources into digital signals that can be processed by the CPU (central processing unit). If the sound card or driver goes into some kind of malfunction, it would stop working and the computer might even shut itself off.

If you have a sound card connected to your system, then that card will work fine until you open up a program like Audacity and start cutting out sound or adding some effects to it. 

When you open up your sound card and try to use it with Audacity, you’ll get an error message saying that the sound card won’t work. This is because Audacity is altering the sound file that your computer is expecting from the sound card.

If you follow a few steps, you will see that it is fairly easy. Sometimes, a system update can resolve the problem.

Solution 1: 

If your computer has started acting weirdly or locking up, or if you’re experiencing a crash or error that requires rebooting, there are a couple of things that you can do. First off, don’t panic. Restarting doesn’t always work, but most of the time it will. Second, check for updates. Updates can fix problems that might have caused these issues.

Solution 2:

The problem may be in the audio drivers of the OS. Try turning off all audio applications and restarting your computer. If it still doesn’t work, try updating your OS.

Solution 3:

Click on the ‘Go’ button, and then select the ‘Systems Preferences’ option. Next, open the ‘Disk Utility’ section, and then select your hard disk. From the list of options on the left, select ‘Repair Disk Permission. Sometimes, the corrupted permissions are to blame for issues with the audio.

Solution 4:

Select the ‘System Preferences’ from the dock. Then select the ‘Hardware’ option from the ‘Preferences’ section. Then click on the ‘Sound’ tab. Next, ensure that the correct output device is selected.

For example, you might see the word Internal on a menu option in the lower-left corner. The ‘Mute Checkbox’ option is in the lower right corner. Make sure it is checked. If you do not see this option, contact a support representative.

Solution 5:

Click ‘Go’ and open the ‘Terminal’ window. Then, type in the following command: ‘Sudo apt-get install alsa-tools’. After it’s installed, press enter. Then type in ‘mixer -c0 set Master 100%, Headphone 75%’ and press enter. This will reset your sound.

Why Is My Macbook Pro Speaker Buzzing?

Strange buzzing sounds can come from your Macbook Pro speakers. While you’re typing away, there are times when a strange sound may come from your speakers. This could be because of dust, wrong audio settings, damaged speakers, or PRAM (Permanent Recording Address Memory) failure.

  • Damaged speakers
  • Settling of dust
  • Problem with the audio settings
  • Issues with the SMC or PRAM

How To Fix The MacBook Pro Speaker Making A Buzzing Noise?

To fix the buzzing noise in your MacBook Pro, you need to clean any dust or dirt on your MacBook’s fan vents and on the fan itself. You can use compressed air to do this.

Clean Your MacBook:

With time, dust settles inside your MacBook near the fan blades. This disturbs the normal flow and causes buzzing noise as the fan spins. The problem can be easily resolved by dusting the fan blades. Here is how:

  • The first step is to turn off your laptop. Once it’s turned off, fans shouldn’t spin and it’s time to check the bottom.
  • You’ll need an air compressor to blow out the dust and dirt from the underside.
  • The dust will settle on the fan blades and clog them up.
  • With a screwdriver, remove the two screws holding the bottom cover in place.
  • After you’ve removed the screws, gently clean the dust and dirt that you see.
  • Use the compressed air as a gentle dusting tool.
  • To make sure the fan works properly, you can spray a bit of compressed air from the nozzle directly onto the fan to make sure there aren’t any obstructions.

Since a MacBook Pro is so expensive, you shouldn’t risk damaging it. There are plenty of ways to protect and repair it without a whole lot of work.

Check the vents

Every Apple product has vent holes for the air to be expelled and for the system to get rid of heat. It also absorbs cool air. This is important for keeping the system in good condition.

Be aware that fans don’t just run automatically. You can open or close them yourself, so make sure to check regularly if they need cleaning or adjustment.

A blockage is often what’s making the buzzing noise. That could mean the fan is dirty or clogged with something else. In some cases, the fan itself is not working or damaged. If the vents are blocked, you should try cleaning them or replacing the fan altogether.

Ventilation is a great way to cool off any system and increase efficiency. However, if the vents and fan are blocked, your computer can overheat and even shut down. Cleaning these vents and fans is a good idea for optimal performance.

MacBook Pro Making A Popping Noise

Some users report a strange popping sound coming from their MacBook Pro devices. While these incidents seem rare, it’s always a good idea to keep an eye out for similar issues if you own one of these computers.

A popping sound can be described as the cracking or popping sound of a small item. It’s heard when the air pressure inside a closed object exceeds the pressure of the outside environment. 

This is most noticeable with a pop or cracks when a plastic bottle is squeezed and released. Pop sounds can occur at any time with different noises and different frequencies, but they are usually associated with small items that contain air.

There are many causes of the buzzing noise that occurs when you plug a new device into a computer.

  • Some speculate that heat is one of the reasons.
  • The new model of the 15-inch MacBook Pro is a significant upgrade from the previous generation. It’s not only thinner and lighter but also has a higher-resolution Retina display, the latest Intel processors, and faster storage.
  • Others say that this noise was occurring when a dent on their MacBook was hitting the fan. While this usually requires a bit of physical work, they don’t have to worry about it falling under the ‘user-inflicted’ category.


Reformatting the hard drive or reinstalling the operating system usually doesn’t work in the end. You need a different approach.

There is an increasing number of cases where MacBook Pro owners are complaining about a popping sound, but thankfully, it doesn’t cause any harm to the computer.

Thermal expansion and contraction is common issue in electronics and is most likely caused by heating the board and components. Apple’s warranty covers the issue, and you should file a claim if your iPhone screen is getting damaged due to heat.

MacBook Pro speakers making static noise

The static noise typically occurs because of a configuration change. A configuration change could be an upgrade, a new OS installation, a software update, or other software. The change may be so minor as not to be immediately noticeable to you but it can be quite distracting for those working on your system.

  • Open System Preferences, and select Sound.
  • Make sure you check the output option to make sure it matches your application. Often, you’ll want to use a particular file type to store your output. But, this isn’t always the case.
  • Select “Output Mode” and then select “Internal Speakers” or any other speaker type.
  • Try again and give it another go.

There may be times when you find that you cannot use the SoundFlower extension on your device, or that it simply stops working. This may happen either as a result of an updated system or simply because your device has run out of space.

If you’re seeing static on your headphones, chances are they are getting a bit worn out, but there are a few things you can try to fix it.

If you hear the same noise when you connect it to any other device like your smartphone, the problem is probably with the wiring of your external speakers. You should look for a replacement or repair it immediately.

If you haven’t been able to get it to work on your Mac, it could be that there is a hardware or software issue. That means it is time to head back to your Macbook’s settings and make sure it is running correctly.

  • Open the System Preferences dialog and click the Sound option to find Sound Effects settings.
  • This shows all the sound effects that can be used when the system boots, shuts down, etc.
  • Check your volume control or audio settings. You could also try turning off the “Play Feedback when Volume is Changed” option.

A Bluetooth connection can be used to transfer files, music, or even take phone calls. If you’re experiencing a static noise on your Mac’s speakers, Bluetooth connections might be the culprit. You’ll need to check for other connections that could be causing the issue.


These are just some of the many ways you can fix a crackling/buzzing/popping sound on your MacBook Pro. If your Mac is experiencing any of these sounds, you should try these tips to fix the issue. Hopefully, the tips above will help you fix your MacBook Pro’s speaker noise.
