6 Solutions to Common Audio Issues on MacBooks

MacBook audio issues can range from garbled sound to no volume. And these issues are more frequent, particularly when your laptop is operating on an older version of macOS. 

What makes them annoying is that they occur out of nowhere. You are left with no option but to stop what you are doing and look for ways to fix it. 

More often, incorrect settings or misconfigured apps are the reasons for audio issues. As a result, you do not hear any sound from the internal speakers or headphones.

If you are experiencing a similar audio glitch, scroll through the article to learn the ways to fix sound-related issues on MacBook. 

Check the Volume

The sound issue can be non-existent, so before you spend your valuable time searching the web, check the volume. Yes, you heard it right; check the volume settings on the MacBook and make sure you have not set it to mute. It is normal to mute the volume while working on important projects, so that might be the case.

Use the volume slider in the menu bar to adjust the MacBook’s sound. Alternatively, press and hold down the F12 key to raise the volume. There might be a problem with the individual app you are trying to play, so make sure to check the volume indicator before you play anything. 

Check External Drives

After connecting external speakers, if you are still hearing sound from the internal ones, check if the device is properly connected. Some older versions of the external speakers failed to receive sound via the HDMI port. If you have connected wireless speakers, the chances are that the mac os monterey bluetooth not working is a problem that you need to fix.

Make sure that the speakers are compatible with the MacBook. If possible, change the connectivity port. Check if the external device is displayed in the list of connected devices in the Output tab. To check this, navigate to Preferences, click Sound, and then select the Output tab. 

Select the Right Audio

If you are not able to listen to the audio even after connecting the headphones, the problem can be the audio bug. Check the input and output settings of the audio device to check that the right device is selected. 

Sometimes, the computer picks the wrong device due to inaccurate configuration settings, third-party app conflicts, or driver incompatibility. 

In that case, navigate to the Apple menu, select System Preferences, click Sound, select the Output tab, and tap the right audio device. Alternatively, navigate to Sound, click Sound Effects and select your output devices from the Play sound effects through the drop-down menu.

Update Apps Often

Third-party plugin integration can cause sound issues on the MacBook. Hardware and software incompatibilities can often be seen in third-party audio streaming or video streaming apps. So, if you are trying to listen to a podcast on Spotify, make sure no updates are pending to install as they may affect the sound. 

Similarly, if you are trying to watch a movie on a MacBook and you can hear or see anything other than a black screen, update the app immediately. 

There may be the latest updates waiting to get installed on the system. Keep a regular track of updates and ensure to install them as soon as they are available. 


NVRAM (Non-Volatile Random Access Memory) on MacBook is a small memory unit that macOS utilizes to store various settings. These settings include but are not limited to the volume, startup disk selection, time zone selection, and display resolution. Resetting the non-volatile RAM can help clear some common technical glitches. 

However, you can only reset NVRAM on the previous versions of MacBooks as it is not an option on the M1-powered devices. The latest MacBook models will auto-check NVRAM, and if required, it will reset it automatically on boot up. 

Check Hardware and Ports

After checking all the options, if you are still not able to listen to audio or hear a muffled sound, then the connectivity ports might not be working. 

In that case, either the ports are damaged, or the device is unrecognizable. Also, there might be an issue with sound drivers, and you may need to update them. 

While upgrading drivers, don’t forget to visit only the legitimate links and websites. If the port is damaged, you will need to visit AppleCare Center for professional assistance. Fixing a damaged port is not easy, and you may need to replace it. If you have an AppleCare+ subscription, you may get it replaced for free. 

The Conclusion 

Technical glitches in digital devices can occur at any time without displaying any prior symptom. Fixing several sound issues is easy, and you can rectify them by yourself. However, if there is damage or incompatibility, you may need to resolve them via a more advanced workaround.
