One of the most common reasons why sound isn’t working on a Mac is because the volume is turned down low or muted. Make sure that your Mac’s volume is turned up by checking the volume icon on the menu bar or the sound settings in System Preferences. If the volume is muted or turned down low, increase it and try playing audio again.

Audio Output is Set to Wrong Device

If your Mac’s audio output is set to the wrong device, there won’t be any sound coming out of your speakers or headphones. To check the audio output device, go to System Preferences and click on Sound. From there, select the Output tab and ensure that the correct device is selected. If the wrong device is selected, switch to the correct device and try playing audio again.

Audio Output Jack is Dirty or Damaged

If your Mac’s audio output jack is dirty or damaged, it can prevent sound from coming out of your speakers or headphones. To clean the audio jack, use a soft-bristled brush or compressed air to remove any debris or dust. If the audio jack is damaged, you may need to get it repaired or replaced by a professional.

Audio Settings are Corrupted

If your Mac’s audio settings are corrupted, it can cause sound issues. To fix corrupted settings, reset your Mac’s PRAM (Parameter Random Access Memory) and SMC (System Management Controller). To do this, shut down your Mac and then press and hold the Command + Option + P + R keys until you hear the startup sound twice. Then, release the keys and let your Mac boot normally.

Audio Drivers are Outdated or Missing

Outdated or missing audio drivers can also cause sound issues on a Mac. To check for updates, go to the App Store and click on Updates. If there are any updates available for your Mac’s audio drivers, install them and then try playing audio again. If the audio drivers are missing, you may need to download and install them manually from the manufacturer’s website.

Application Settings are Incorrect

If the sound isn’t working in a specific application, check its sound settings and ensure that the correct device is selected. You may also need to check the application’s volume settings and increase them if necessary.
