How to Fix Sound Problems on macOS: No Sound, Cutting Out, Safari

If you have been bothered by sound problems since upgrading macOS to its latest version, we will tell you how you can fix this problem. What are the most common macOS sound problems? Shall we take a look? The cause of this problem may be the upgrade you made, in which case you may have started to be unable to hear many sounds. Here is the macOS/MacBook sound problem fix!

macOS Sound Features Not Working! MacBook Has No Sound 2023!

After upgrading macOS, you may notice that your sound has cut out completely. In this case, you get no sound at all from the speakers you used before the upgrade. It does not matter which video or app you open; you cannot hear anything. You can try adjusting the sound controls, unplugging and replugging your speakers and playing media on a different device. However, you are likely not to get a productive result in that case either.

When macOS is first launched, it sometimes does strange things when assigning speaker outputs. Fortunately, this problem is easy to fix. Open the System Settings app from the Dock or the Apple icon in the menu bar, then click Sound in the sidebar. Here, you will see a tab called Output. In this tab, you should see options for choosing a sound device. Try setting the sound to Internal Speakers. Make sure your output volume is on and the Mute option is not checked. Sound effects are set to your device's speakers. This will restore sound to your Mac's native speakers. In the Output list, you will see options for all these devices as long as they are connected. Select the one you want to use. When loaded on a computer connected to HDMI speaker systems, macOS can get confused about which speaker to select automatically. To get around this problem, select your speaker options manually.

How Do You Fix macOS Sound Cutting Out?

If macOS randomly cuts the sound and then restores it for no reason, there may be a problem with the way your computer uses memory. First, make sure the problem cannot be narrowed down to a specific app or service. You can open Activity Monitor and then select the %CPU column to see which apps are occupying your memory. Make sure the arrow next to %CPU points down; this feature shows your most memory-hungry apps at the top. Select the app and try restarting it, then select the Stop button at the top of Activity Monitor to see whether your sound gets fixed.

If the problem is shared across all sound sources, you may need to reset your PRAM (random access memory) parameter, which Intel-based Macs use to get the basic settings for your Mac and connected devices. If you use an Apple silicon Mac, try shutting down, waiting a few seconds and then restarting.

If your Mac has an Intel chip and you want to reset its PRAM, start by restarting your Mac, then immediately press the Option + Command + P + R keys at the same time. Keep holding these four keys for about 20 seconds. During this time, your Mac may restart and you may hear the startup sound more than once. After this process, your PRAM will be reset.

You may need to review System Settings to reset any of the customized settings you had before.

macOS Safari Sound Not Working 2023!

If your tests revealed that the sound problems are mainly in Safari, this may be another settings issue. In this case, sound works in other browsers such as Chrome, but not in Safari.

If you visit System Settings > Sound, you can probably check your Output option, which lists various device options for sound output. If one of these options is Soundflower or something similarly unusual, it is a sign that macOS may be using the wrong sound output. Change the output to Internal Speakers or another speaker device you want, then try Safari again. The problem will be fixed.
