Mac users may find that their sound and audio output do not work, causing the Mac to become totally silent and it is no longer responsive to the volume controls. This issue can be quite baffling and problematic.
If you are encountering issues regarding Mac’s sound, then there are a few ways to troubleshoot the problem. Let’s quickly go through the different methods to fix the sound not working in Mac issue.
- Reboot the Mac
One of the most frequently suggested resolutions to any software or hardware issue is to conduct a simple reboot. At times, restarting the Mac does troubleshoot the sound issue you are encountering. Therefore, when even you face a sound not working issue, the first thing you should do is to restart the device.
- Plug and unplug earphones
Are the volume options grayed out? IS there any red light being emitted from the headset’s jack? If yes in either case, then just unplug the Apple headsets and insert them back again. Do this a couple of times. This solution has worked for many people. This is due to hardware issues, and as time passes, this is likely to get worse. Therefore, in order to get completely rid of the problem, take your Mc for servicing.
If you are using non-Apple earphone or headphones, then you may try switching to Apple headsets and see if it solves the issue.
