If you’re having audio issues with your MacBook Air, there are a few things you can try to troubleshoot the problem. First, make sure that your computer’s volume is turned up all the way by checking the System Preferences > Sound > Output tab. If you still don’t hear any sound, try restarting your computer and testing the audio again.
If you’re using external speakers or headphones, make sure that they’re properly plugged into the headphone jack on your MacBook Air. It’s also a good idea to check if your speakers or headphones are working by plugging them into another device such as an iPhone or iPad.
If you’ve tried all of these troubleshooting steps and you’re still not hearing any audio from your MacBook Air, there may be an issue with the internal speaker itself. You can try resetting the SMC (System Management Controller) to see if that helps resolve the issue. If resetting the SMC doesn’t work, you may need to take your MacBook Air computer to an authorized Apple service provider for further diagnosis and repair.
