On your Mac, your volume button allows you to increase the volume of sound when you’re listening to music or watching videos on the web. There’s usually a set volume you can increase it to and if you don’t want any sound to come out of your Mac, you can mute it.
Unfortunately, the volume button can remain on mute and be grayed out so that you can’t adjust the volume. This problem is hard to troubleshoot because you’re not told the source of the problem and volume problems on your Mac aren’t common.
The Reason the Volume is Grayed Out
The reason why the volume button is greyed out and locked on mute is that there’s a problem within your random-access memory parameter. Since these settings store information about your volume, if there’s a problem within these settings, it causes your volume to stay on Mute.
1. Reset PRAM
The P-RAM on your Mac stands for parameter random access memory and it is a memory that is found on your Mac that store system settings. The PRAM can store settings like, screen resolution, speaker volume, startup volume choice, time zone settings, and color depth. Since these settings store information about your volume, resetting it might fix the problem.
To reset the PRAM:
1. Reboot your Mac.
2. As soon as you hear the chime, hold down Command + Option + P + R. The next time you hear the boot chime, the PRAM should be reset.
3. Wait for the Mac to boot up.
4. Update your Mac. After you’ve reset your PRAM, you can check if you’re able to change your volume.
2. Reset MVRAM
After you’ve reset your PRAM, if your volume is still locked, you’ll need to reset your NVRAM. Your SMC is a small memory that your Mac uses to store certain settings. Resetting the NVRAM can help fix problems with your volume settings.
1. Shut down your Mac. Locate Hold Command (⌘), Option, P, and R and be ready to hold them.
2. Turn on your Mac.
3. Press and hold the Command-Option-P-R keys once you hear the startup sound.
4. Hold these keys your Mac restarts and you hear the startup sound again. Check if your WIFI is working and if the error message has gone.
3. Reset Core Audio
Core audio is a low-level API that deals with sound on your Mac. Resetting it can help fix the volume problem on your Mac.
To Reset Core Audio:
1. Launch the Terminal.
2. Enter the command sudo killall coreaudiod

Every day is a great time to listen to your favorite tunes and some truly sick beats on your MacBook Pro. Out of the blue, however, you may find that your trusty laptop sounds unwell. Songs and videos coming from various apps and browsers, for instance, might sound terrible.
Audio issues aren’t at all a rare occurrence for MacBook Pro users. Users online have documented their issues with the MacBook Pro speaker, where they encounter a sizzling noise, speakers crackling, or a popping sound straight from the machine.
Here’s a quick guide to navigate these strange sounds coming from the MacBook Pro speaker and recover the good listening experience you’ve had before.
Weird Noise on MacBook Pro: Troubleshooting the Problem
That weird noise on MacBook Pro can be caused by many different things, such as damaged or blown speakers, audio settings gone wrong, or a temporary issue that you can resolved when you reset the PRAM and SMC. After Apple released the MacBook Pro with a new feature known as Touch Bar back in 2017, forum users shortly came out to complain about a popping sound – their common denominator was owning the MacBook Pro with Touch Bar, albeit bought at different times and with various manufacturing dates.
It’s important to properly troubleshoot the sound problem to identify whether it’s caused by hardware or software, or if it’s merely a system update that can tackle the sizzling or popping sound. First, determine if it’s the speakers or the audio settings at fault. Plug in your headphones and start listening to anything with sound. If the sound comes across as clear on the headphones, then that means the problem is related to software. Blown speakers, for instance, may crackle at high volumes.
If your audio woes happen only while you play specific songs, videos, or other files, then it’s likely that the files are corrupted or suffer from low quality. If the problem persists, too, even if you listen from a CD or DVD and not directly from your hard drive, then you can proceed to troubleshoot the sound settings.
Before you try one of the fixes we provide below, make sure to always keep your MacBook Pro in tiptop shape by diagnosis your system regularly, cleaning out junk, and eliminating space hogs using a reliable Mac repair tool.
How to Solve Speakers Crackling and Other Audio Issues on MacBook Pro
Here are some methods you can try to solve the sound problem on your machine:
Checking Audio Preferences
Expect audio issues when the speakers on your laptop are set incorrectly in the preferences. Follow these steps:
- Unplug all external devices from the USB, FireWire, as well as 3.5 mm audio ports.
- Open System Preferences, and then click Sound > Output tab.
- Choose Internal Speakers as the default option. If there are no other options, choose Internal Speakers to ensure that the option is selected anyway.
- Slide the Balance slider left or right while audio is playing in order to test if just one speaker’s not working right. If the problem happens while the slider’s all the way in either direction, then it means one speaker is damaged and needs to be repaired.
Reset your PRAM and SMC
Reset your Parameter Random Access Memory (PRAM) and System Management Controllers (SMC), which you can do by booting your computer while you hold down the Command, Option, P, and R keys simultaneously until you hear two chimes. Here are specific steps:
- Shut down your laptop.
- Turn it on again using the power button. Immediately press and hold the Command + Option + P + R keys. Wait until you hear the startup chime twice.
- Reset the SMC by shutting down your laptop, making sure that the power cable remains plugged in.
- Simultaneously press and hold Shift + Control + Option on the left side and the power button for five seconds.
- Release the keys and turn off your computer.
Installing macOS Updates
Some Mac OS X users reported hearing their speakers crackling after the 10.4.10 update, even though their speakers weren’t at all broken. To address this, update your OS to its latest version in order to patch any audio issues. Your audio woes might not be the result of your last update, but getting the most recent update just might be key to solving them.
Final Notes
Audio hiccups on your MacBook Pro can be totally annoying, but can signal a more serious problem as well. Electronics that produce a sizzling sound when electrically connected, for one, should be a red flag. It’s important to unplug it if it persists, remove the battery, and contact Apple support for assistance.
