I'm all for sharing 'the basics' for audience members who area simply new to a platform, however I've grown to know Mac OS X Hints to generally offer a higher standard of how-to.
For this hint in particular, I'm surprised to see two verbose paragraphs which fail to mention several fundamental exceptions. For one, alarms (set by the Apple Clock app) override the silent toggle as do timers. Also, as mentioned by another commenter above, there is no mention of how to further ensure your iPhone will be silent by turning off Emergency and Amber alerts. Even then, I would have thought MacOSXHints would have pointed out, for the benefit of their readers, that unless disabled FindMyiPhone will *always* have the ability to make the phone chirp.

If the sound on your Mac has stopped working, there are several possible explanations and solutions. The first thing to check is that the sound definitely is not working. Below we'll explain what to check.

No sound on Mac? Check these things first

This is a list of operating systems.Computer operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. Criteria for inclusion is notability, as shown either through an existing Wikipedia article or citation to a reliable source. Ever since the computer did an update volume will randomly get quiet even though it is at 100%. Ive tried uninstalling and reinstalling the driver multiple times, I've rand the audio troubleshooter multiple times, I've done ever suggestion i've found online with no improvement.

1. Check the volume

As simplistic as it may seem, the first thing to check is that the volume hasn’t been muted intentionally. Tap the volume up (F12) key to turn up the sound level.

Pro tip: If you hold down Option+Shift when you press F12 or F11 to increase or decrease the volume, it will move in smaller increments than the full step changes that occur when you use the keys on their own.

2. Is it an app problem?

It may be that there’s no sound on your Mac because it won’t play audio in a specific app. If, for example, you can’t hear sound from a video in Safari, make sure the audio isn’t muted by clicking the volume control in the video. You should also check other sound sources, like iTunes and QuickTime movies, to find out if they can play sound.

Tip: if you’re fed up with websites you visit automatically playing video with sound when you’re working, go to Safari > Preferences and click the Websites tab. Click Autoplay, and in the bottom right of the window, choose Stop Media with Sound.

3. Run Maintenance scripts

If you’ve determined your Mac’s sound definitely isn’t working, consider running CleanMyMac X’s and its tool called Maintenance scripts. This is a popular app for do-it-yourself Mac troubleshooting. What are Maintenance Scripts? These optimize the performance of your Mac by running a number of routines such as repairing disk permissions, verifying your startup disk, and rebuilding the launch services database.

Here's how to run Maintenance scrips:

Download CleanMyMac X here (it's free to download).

1. Launch the app.
2. Click Maintenance.
3. Choose Run Maintenance Scripts and click Run.

4. Check for hardware issues

Next, check there’s nothing plugged into the headphone/line out port and look to see if there’s a red light on that port. If there is, it could be there’s a problem with the port or something blocking it. Try blowing on it to clear dust, if that’s the case.

5. Are you running the latest version of macOS?

If there’s still no sound on your Mac, Apple’s advice is that the first thing you should do is make sure you’re running the latest version of macOS.

To check which version of macOS your Mac is running, click the Apple menu and then About this Mac. The window that opens will have the name of the version of macOS currently installed at the top. Now the latest version is macOS Big Sur. If you’re not running Big Sur, you should consider installing it by going to the App Store app and clicking on it in the sidebar on the right-hand side of the main window.

If you don’t want to install Big Sur, at least make sure you’re running the latest update to whichever version of the OS is installed. To check that, click Software Update in the About This Mac window. That will check for updates and let you know if there’s one available. If there is, install it.

Before installing either a new version of the OS or an update, back up your Mac using Time Machine or whatever backup tool you normally use.

How to check your sound settings

If you’re running the latest macOS version and your sound still isn’t working, the next step is to check your Sound settings.

1. Click on the Apple menu and choose System Preferences.
2. Click on the Sound pane.
3. Select the Output tab and choose built-in speakers. If that’s not available as an option, contact Apple Support.
4. Check if the volume slider is low; if so, slide it to the right and recheck the sound.
5. Make sure the Mute box isn’t checked.

If you check your sound settings, you see a USB device selected rather than built-in speakers, and you can’t change it, disconnect all USB devices from your Mac and try again.

Is there an app interfering with the sound?

Some applications, like screen recorders, install their own audio output drivers so that when you record the screen, you can direct your Mac’s output to the recording app. It’s possible that if you’ve installed an app like that, its driver could be interfering with your Mac’s sound output.

1. Go to System Preferences and choose Sound.
2. Click on the Output tab.
3. If there’s an output option that looks like a software app and it’s selected, that may be why the sound is not working on your Mac.

The best thing to do in that instance is to uninstall the app. You could just drag the app to the Trash, but that won’t uninstall it properly or remove all the files the app has placed on your Mac. To do that, you should use a dedicated uninstaller like CleanMyMac X.

CleanMyMac X makes it very easy to completely uninstall any app so that it doesn't leave any fragments or stray files behind. By using CleanMyMac X, you can be sure you’ve deleted all the files associated with the app and that it hasn’t left anything behind. You can download CleanMyMac X for free here.

Restart the sound controller

Mac sound not working still? If no software audio drivers interfere with your Mac’s sound output, nothing plugged into the headphone jack, USB, or Thunderbolt ports, and your sound still doesn’t work, the next step is to restart the sound controller. This requires launching Activity Monitor and quitting a process, but don’t worry, it’s not too scary!

1. Go to Applications > Utilities and double-click on Activity Monitor to launch it.
2. In the search bar, type 'coreaudiod’ to locate the Core Audio controller.
3. Click on coreaudiod, then click ‘X’ in the toolbar to quit it.
4. Coreaudiod will restart.

Why is the volume low on Mac?

If you've faced issues with the speaker volume on your Mac, it's likely a software-related problem. Maybe some app conflicts with your speaker settings, or maybe there's something else. The first thing you can do to troubleshoot the issue is to reset NVRAM/PRAM. These are small parts of your Mac's memory that control sound volume, time zone, display resolution, and other settings on your Mac.

To reset NVRAM/PRAM, shut down your Mac, and press Option-Command-P-R on its start-up. Release the keys after about 20 seconds. After your Mac restarts, check if the volume is back to normal.

Mac volume not working and stuck on mute?

If the volume control is not working on your Mac, either using the keyboard or the slider in the menu bar or System Preferences, it could be ’stuck’ on mute. The most common occurrence of this problem is on pre-2015 Macs that had digital audio output support in the headphone jack.

On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in. The Mac would then change the output to headphones or digital output accordingly. However, sometimes the sensor failed to recognize when a digital audio device had been unplugged, and so the audio output remained locked on digital output, with no way to change it. With no digital audio output connected, there is no way to change the volume or hear a sound.

In that case, the solution is to plug the cable back into the socket and remove it again.

Some people recommend that you do both at the same time: click on the device name in the Sound pane, and unplug the audio jack/usb connector. The Mac's logic board seems to have trouble switching off between two output modes. In this case, you may try to reset SMC (see the next step).

Try it a few times, if necessary, to ‘trip’ the sensor and make the Mac recognize the digital audio device is no longer connected. If that doesn’t work, there could be some gunk blocking the socket. Try blowing on it to remove any dust. If that doesn’t work, buy a can of compressed air and, carefully, spray the socket to bow out the dust.

If that still doesn’t do the trick, buy a foam-tipped swab (don’t use a cotton bud as these leave tiny threads behind) and dip it in rubbing alcohol. Put the swab into the headphone jack and clean it, wiping away as much of the link as possible.

Reset the SMC

Another built-in controller that may affect sound is SMC (System Management Controller). It's possible to reset, it only takes a minute.

1. So, shut down your MacBook completely.
2. Hold down Shift + Control + Option keys and press the Power key.
3. Keep holding all these keys for 10-15 seconds.
4. Start your Mac normally.

Bluetooth sound not working on Mac

Your Mac can play audio wirelessly via Bluetooth, so if you have Bluetooth speakers or headphones, you can use those to listen to music or anything else on your Mac. Sometimes, however, they don’t work.

Make sure Bluetooth is switched on

1. Go to System Preferences and click the Bluetooth pane.
2. If it says, Bluetooth turned off, turn it on.

Make sure your headphones or speakers are connected.

1. Look in the list of devices in the main window to see if your headphones or speakers are listed.
2. If not, put them in pairing mode (you’ll need to refer to their instructions to find out how to do that) and when they appear, click Connect.
3. If they are listed but not connected, make sure they’re switched on and Control-click on them in the main window and choose Connect.

Tip: If you check the box labeled Show Bluetooth in the menu bar in Bluetooth preferences, you can connect from the menu bar item.

Once your headphones or speakers are connected, click on the volume control in the menu bar and choose them. If you don’t have the volume control displayed on the menu bar, go to System Preferences, choose Sound and then the Output tab and select the Bluetooth speaker or headphones. While you’re there, it’s a good idea to check the box labeled Show volume in the menu bar — it’s in the Sound Effects tab.

To conclude, there are a number of reasons why the sound is not working on your Mac. If you follow the guide above and take it one step at a time, you should be able to fix the problem. If none of the steps above work for you, the next step is to contact Apple support and, if possible, make an appointment at the Genius Bar of an Apple Store. Finally, it wouldn't harm if you check your Mac for malware and remove system junk with the mentioned app, CleanMyMac X. The basic system cleanup may help you to get your audio working again.
