If your Mac has audio problems, or when you’ve selected a playback device that doesn’t have sound, apply a few quick fixes before taking it to Apple’s technical support (also known as Apple’s technical support). Genius Bar). Sometimes we just need to plug in and unplug the headset, the sound can also work again. Or, simply resetting the PRAM (memory on Mac computers) can fix quite a few audio-related problems. Even when the latest version of OS X is updated, sound problems caused by system errors can be resolved.

Plug in the headset then pull it out. If audio control is disabled, or you see a red light in the headphone jack, plug the end of the headphone cable in and out a few times. This will solve the problem and restore the sound. [1] X Research Source
- Note: This is a sign of hardware failure so you need to do this several times until it’s ok. Then, bring the computer to Apple service for a thorough repair.
- Some users have reported that using Apple headphones makes the process more efficient.
