Fix 5: Check and Reset the NVRAM on Your Mac

The older MacBooks were known to use the PRAM, where the P stands for the word "Parameter." As this terminology is directly pointing to the Random Access Memory of the Mac, problems across it are quite uncommon among Mac users. Problems in start-up and other functions, including the sound of the Mac, may arise due to issues across the RAM. As modern Macs use the NVRAM as an alternative, the process of having them reset is similar to that of the PRAM.

We shall look at the resetting techniques for both the M1 Chip MacBooks and Intel Chip MacBooks. To resolve the problem of audio on mac not working, it is perfect for trying out these simple steps for effective resolution:

For M1 Chip Mac

If you have a MacBook Pro or Air with the M1 Chip, you need not worry about resetting the NVRAM on the device. The NVRAM is automatically tested across the startup across the Mac, and if there are problems across it, they are automatically resolved. However, if you feel that the Mac is not functioning properly, you can restart your Mac so that it re-assesses and inspects the NVRAM for any error.

For Intel Chip Mac

Users who have MacBook Air or Pro with an Intel chip should follow the steps as shown below:

Step 1: You need to turn off your Mac.

For this, go across the Apple icon on the top and select the 'Shut Down' option.

Step 2: Restart the Mac by pressing the "Power" button.

As the Mac turns on, use the shortcut key of "Command-Option-P-R" and hold this for about 20 seconds.

Step 3: Let the Mac start normally.

Once it is turned on, check the Startup Disk, Display, Date, Time, and System Preferences for any irregularities. Also, try to turn on the audio and check if it is working properly.

Core Audio on Mac is designed to power up the sound inputs and outputs across the device. Therefore, there is a chance that the problem of MacBook no sound won't resolve, which then requires restarting this component to resolve the issues on your Mac.
