There is also a tendency that your Mac volume is not working because it does not play on a specific application. Let us say that you were not able to hear a sound using your Safari so you have to check if the audio is not muted. You can also try to check for your other resources like your iTunes if the sound is playing or not.

3、 See for Any Hardware Issues
Here, you have to check if there is nothing plugged into your Mac like headphones or line out. Also, check your ports if there is a red light indicated on it. Once that you saw a red light on your port, then that means that there is something blocking it. For this, you can try to blow on your port for you to remove anything that is blocking it like specks of dust.

4、 Check if You Have the Latest Version of Mac OS
If you have already checked all the things that are mentioned above and you still have no sounds on your Mac, then you have to check if you have the latest version of Mac OS installed. This is actually what Apple suggests in this kind of situation.

For you to check the version that you are currently using, just go ahead and click on the Apple menu and then click on the About This Mac. A pop-up window will then launch on your screen where you can find the name of the version of your Mac. As of now, the latest version that Apple has is the macOS High Sierra.

This scenario usually happens on pre-2015 Mac because it has digital audio output support in its headphone jack. For this type of Mac, what usually happens is that once the sensor in the ports detected that there is a headphone jack or digital audio device that is plugged in, then it will change its output to whatever that is plugged in.

But, there are instances that the sensor fails to detect whether there is an audio device that is plugged in that is why it is locked on the digital output. Since this case cannot be changed, what you can do is to plug a cable to its socket several times. You can also try to trip the sensor for you to make your Mac recognize that there is no audio device connected.

If this does not work, then there could be gunk blocking your socket. If so, you can try blowing your socket for you to remove any dust or you can also get a can of compressed air and then gently spray it to your socket to remove that dust. You can also use a foam-tipped swab and have dipped in rubbing alcohol. Use this to clean your socket. Do not use a cotton swab because it will leave tiny threads behind.
