Common Causes of Macbook Microphone Not Working

Before we delve into the solutions, let’s explore the possible reasons why your Macbook’s microphone is not working. Here are some common causes:

1. Hardware Issues

Sometimes, the microphone may stop working due to a hardware fault. Check if there’s any physical damage or debris that might be blocking the mic. Also, ensure that your Macbook is not muted or that the volume is turned down low.

2. Software Issues

There could be software issues causing the microphone to stop working. Check the Audio MIDI Setup to ensure that the microphone is not turned off or the settings are not changed. Make sure that the drivers and microphones are up-to-date and compatibility is not an issue.

3. Application-Specific Settings

Sometimes the microphone may stop working as a result of application-specific settings. This means that the microphone is working as expected, but the settings of a particular application may not be configured correctly.

How to Fix the Macbook Microphone Not Working Issue?

Once you have identified the cause of the problem, try the following solutions to fix it:

1. Check System Preferences

The first step to fix the microphone issue on Macbook is to check the System Preferences. Go to the Sound preferences, and then select the Input tab. Ensure that you have selected the correct microphone. If it’s not selected, select it from the list.

2. Reset PRAM and SMC

Resetting the PRAM and SMC can help resolve issues with the microphone. The PRAM stores the microphone settings, while the SMC controls the hardware functions. To reset the PRAM, hold down the Option + Command + P + R buttons simultaneously during startup. For resetting the SMC, shutdown your Macbook and hold down the Shift + Control + Option + Power button for 10 seconds.

3. Disable Ambient Noise Reduction

Ambient Noise Reduction could be a reason for microphone failure. Go to the Sound preferences and select the Input tab. Uncheck the “Use ambient noise reduction” option.

4. Use Terminal to Reset Core Audio

If the microphone is still not working after trying the above methods, the issue might be with Core Audio. To reset Core Audio, go to Utilities > Terminal, and type in the following command:
sudo killall coreaudiod
