Microphone issues on MacBook

You're preparing for an important Zoom meeting and want everything to go smoothly. You've gotten dressed early, positioned your laptop at a flattering angle, and made sure that there was enough light.

But when you log in, you find something is wrong! The others can see you on video but cannot hear your voice. Looks like your MacBook microphone is not. working. Quite stressful right?  It’s one of the most common issues with MacBook.

But don't worry. there's generally a quick, simple solution. We will walk you through it. But let’s get started with it.

How do you test the microphone on a Mac? 

Before we jump straight into the solutions, let's make sure that the microphone is actually working. And you are not mistaken. However, there is no need to hunt for third-party applications; instead, you can use the built-in program QuickTime Player. 

Go to the Launchpad and launch QuickTime Player.

In the app's menu, select File and then New Audio Recording.  Make sure to turn up the volume and say something. 

Why isn't your MacBook mic working?

Here are some of the reasons why your MacBook Mic isn’t working properly.

  • The volume is turned down.

  • An app needs permission to use the mic.

  • There's a temporary glitch.

  • Your computer needs a software update.

  • Your Mac has a hardware issue.

What Do to if Mic Is Not Working

There can be a number of Issues causing mic problems ranging from third-party apps or some faulty settings. So, let’s take a look at some tips that can help you if the Mic is not working suggested by the professionals at Fix N Talk, the best MacBook Repairs Adelaide.

1. Check your sound input settings

One of the most popular causes of microphone failure is low input loudness. If the level is reduced to a minimum, your microphone will be silenced. So, when you have microphone troubles, the first thing you need to do is to make sure that the settings are okay

Now, let's start by verifying the settings and making sure they're adjusted correctly:

  • Open System Settings (in Applications, from Dock or Apple menu, via Siri, or using Spotlight Search).

  • ChooseSound.

  • Select Input > Built-in.

  • Here, make sure the Input volume is at maximum.

  • Now, if you speak near your Mac, the Input level bars should fill up.

  • If it's not happening, or the Internal Microphone isn’t an option, then your Mac isn’t registering the mic as an input.

2. Check microphone permissions 

There are cases where an application, such as the Zoom or Skype app, can provide two-way communication with your microphone. However, to use your iPhone mic for any call, voice, or video then the corresponding app must be granted permission to use the iPhone mic, or in other words, the iPhone mic must be on. As stated, one does it when the app is opened for the first time, or the first time since it was closed.

If it was working up to a certain point and then stopped, the only possibility could be that this permission has somehow been removed and you would be required to confirm it. To do it or turn on the microphone on Mac, follow the next step: Go to System Settings. After being on the page, you will need to locate the Privacy & Security link. Next, go to the Privacy tab and find the Microphone in the list of available devices.

To let an app utilize the microphone, switch to the right of the switcher located in that section.

3. Сheck Mac for malware

As was mentioned, there are situations when the mic is not working because of a conflict with a third-party app. At times you may not know whether there is a conflict because you have not installed any new program. Sometimes it could be malware that is complicating Mac’s microphone, therefore scanning for malware would do well to solve this problem.

While malware is very rare on the Mac OS, it is always wise to check your Mac for malware using a cleaner app. We suggest CleanMyMac X as it has an active database of threats, its developer is reputable and it is notarized by Apple. That way, you are sure that the app performs well while using it and is 100% safe from intrusion by third parties.

4. Switch on Dictation

To be more precise, turning on Dictation — even if you don’t plan to dictate something to your Mac — should start launch agents that turn on the microphone and help it get operational.

Right-click the English (United States) icon in the Language bar and click Properties, then go to System Settings > Keyboard.

Go to the place called Dictation and switch it on — to do this, click on the Enable button — this will download files, through which the mic works.

5. Restart your Mac

In general, it should be the first step one is supposed to take in an attempt to fix a range of possible problems. But we all understand that there are various reasons why we do not prefer to restart our computers. Some don’t wish to lose changes that were not saved yet; the others simply don’t want to waste time on reopening all the tabs and applications.

However, they can solve other minor problems such as the mic not working through Mac restarting. Then, without scouring through the Windows Start menu, move to the Apple menu and select Restart. By the way, you may like to know that you are free to click Reopen windows to minimize the time and effort you may spend.

6. Reset NVRAM/PRAM

Another could be erasing the PRAM (Parameter RAM) to its default settings. It remembers many Mac settings, so with this reset, your mic will be working if other things have not turned to normal.

  • If you’re working on a Mac, you can go click the top-left Apple icon and then choose Shut Down.

  • Make sure your Mac has shut down or is at the login/log-off screen.

  • Now press the power button and the following keys (at the same time): When pressed, it can be fixed by holding on to the command + ALT + P + R.

  • Stay in the position for 20 seconds.

  • Try pressing the keys again, and it should start as usual, with the reset PRAM command.
