If the sound on your Macbook pro is not functioning it might be due to technical issues or from your personal settings.
We are going to look into some sound related issues on the Macbook pro and how to fix them.
Turn up the speakers of your system.
First, you need to check that the speakers on your device are actually turned up. You can check it by clicking on the Volume Option in the Menu bar at the top-right corner and turn it up.
Check for earphones.
If you have turned the volume of your speakers up and still no sound then check out for your earphones socket. Make sure there are no earphones connected because if an earphone is connected it won’t give out sound as you will only hear the sound from the earphone.
Check System Preferences.
If there are no headphones and still no sound then check your system preferences. You can do this by following these few steps.
Step 1: Open System Preferences.
Step 2: Click “Sound”.
Step 3: Click the “Output” tab.
Step 4: Click “Internal Speakers”.
Step 5: Check that the mute next to the Output Volume is not muted and make sure that the output volume slider is moved towards the right.
If you have checked the system preference and still no sound then try resetting the PRAM. You can do this by holding down Command-Option P and R. You need to hold them down until your computer starts and chimes before releasing them.
Reset the System Management Controller (SMC).
If the PRAM resetting still does not work then reset the system management controller. You can do this by following these few easy steps;
Step 1: Shut down your device.
Step 2: Plug the MagSafe power adapter to a power source and connect it to your
Step 3: Press the Shift-Control keys and the Power button at the same time.
Step 4: Release all the keys and the Power button at the same time.
Step 5: Turn on the Power button.
Note: If after you have checked all these and accurately did everything but still there is no
sound, then you need to take your device to an Apple store closer to you or look for a
reliable Apple technician so they can rectify the problem.
