Sound Not Working

Hi everyone,

I have a MacBook Air early 2015, the sound is not working. It sometimes turns back on when I restart the computer but not really. It usually it comes up with no input or output devices found when I try to adjust the sound in the settings. Any advice would be appreciated.

Kind Regards

Ana

Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.
