No sound from your MacBook Pro: How to Fix

No sound from your MacBook Pro

Welcome to the topic “No sound from your MacBook Pro: How to Fix”

Audio problems, bugs after and before updating your operating system, issues in connecting an audio device, or low sound are common in Mac, as reported by many users on various occasions. Sometimes, even a misconfigured apps or wrong audio settings can cause such problems in Mac.

Due to these, you might not hear sound from external speakers or headphones. Similarly, you can face static audio or, in some cases, no output at all. Here are detailed fixes to resolve no sound problems on your MacBook Pro. Before calling help, check these things first.

Check the volume

This one is obvious and more of common sense. The first thing to do is to check your volume. Anyone, especially kids, can mute the system intentionally or unintentionally. Just press the volume up or F12 key to view the sound level.

It can be a problem in a specific app.

Quite often, the issue is not in your Mac; instead, the issue persists in a specific app. You might come across an app in which Mac doesn’t play sound. For example, if you are unable to perceive sound from a video in your browser, ensure that it is not mute in the first place.

At the same time, you need to verify that whether other apps in your Mac are playing sound or not. Check other sources, such as iTunes and QuickTime movies, to determine if they are playing sound.

Execute Maintenance scripts

If you are confirming that the issue is in your Mac, not in the app, then we will advise you to consider running CleanMyMac X’s along with its handy feature known as Maintenance scripts. This is a reliable app for Mac troubleshooting.

If you don’t know about Maintenance Scripts? Let me elaborate. These scripts optimize the overall Mac’s performance by executing a number of routines such as disk repairing and fragmentation, disk permissions, checking of your startup disk, and upgrading the launch services database.

Follow these steps to execute Maintenance scripts on your Mac:

  • First, you need to download and install CleanMyMac on your PC, and it’s free to download.
  • Run the app.
  • Click on the “Maintenance.”
  • Now select “Run Maintenance Scripts” and tap on the “Run” button.
  • Maintenance Scripts by CleanMyMac X will handle the rest.

Check your hardware

Next, you need to ensure that there’s nothing plugged into the audio line. Furthermore, look closely to view if there’s a small red light on the audio or headphone port. If you see red light, it means there is some issue in the port or anything is blocking it.

In this case, you can blow the dust from the port using an air blower.

No sound from your MacBook Pro

Do you have the latest version of macOS?

If you still face no sound on your MacBook Pro, you need to follow Apple’s advice and ensure that you are using the recommended or latest version of the Mac operating system.

To check your mac’s version, simply click on the Apple menu and then look for the “About this Mac” option. The pop-up that you will see then contains the macOS version’s name currently installed on your machine. Usually, the name is mentioned on the screen’s top side.

Presently, the updated version is macOS Big Sur. If you don’t have Big Sur, you must install it via the App Store.

Besides, if you don’t want to use Big Sur due to any reason, ensure that you are using the latest and updated version of whichever OS you are using.

To determine your OS version, simply click the Software Update option in the “About This Mac” and then go to the “check for updates.” 

This will show you if there is any updated version is available or not. If you see any updates, download and install them.

Before installing or updating your system, we will advise you to back up your Mac using any software such as Time Machine or whatever backup tool you prefer.

Check your sound settings.

If you have the latest macOS version and the no sound issue still persist, the next thing to fix the no sound problem is to check your Pc’s sound settings. Here is how to do it:

  • First, go to the “Apple main menu” and click on the “System Preferences.”
  • Now, look for the “Sound pane” option and click on it.
  • Choose the Output tab and click on the built-in speakers. If you are unable to see this as an option, you need to contact Apple Support.
  • Now you should check the level of the volume slider. If it is low, slide the bar to the right side and check the audio.
  • Again, ensure that the mute box is not checked.

When checking your sound preferences and settings, you see a USB device in place of the built-in speakers; we will advise you to remove all USB devices from your system and then check the sound.

Is there any application interfering with Mac’s audio?

Some applications, such as screen recorders, often use their dedicated sound drivers, so they will redirect your MacBook Pro’s audio to the app when you are using such apps.

It is common, especially in MacBook Pro. The app’s audio driver interferes with your MacBook’s sound output.

Here is how to deal with this issue:

  • First, navigate to “System Preferences”and pick Sound.
  • Now, click on the “Output”

If the output option looks like an app or software and is selected, this is the problem.

In this case, just uninstall that particular app via dedicated software such as CleanMyMac X.

Using CleanMyMac X assures that you have removed all the items associated with that program and nothing is on your PC.

Reset the sound controller

MacBook Pro no sound error still present? If you are sure that no app sound drivers are interfering with your MacBook Pro’s sound, all audio jacks and ports are free of dust, the next thing you can do to fix the no sound issue is to reset the sound controller.

You will have to launch Activity Monitor and quitting a process. Here is how to do it.

  • First, go to Applications, then go to Utilities and tap on the Activity Monitor to start it.
  • Now, enter ‘coreaudiod’ in the main search bar to find the “Core Audio controller.”
  • Next, tap on the “coreaudiod” and click ‘X’ in the toolbar to close it.
  • Coreaudiod will reset in a few seconds.
