Off – this will disable all sound notifications. I understand it would be more convenient if we could customize the sound setting for all activities in Teams. And Teams needs more powerful and practical features to meet our customers' expectations. So Microsoft puts high value on your ideas and suggestions. Lots of apps can play sound and/or audio but that doesn’t necessarily make them all equal. Apps like media players need to be able to play audio as a core function whereas messengers, or any other app that has audio you cannot turn off may need a mute button. Unfortunately, out of the box, macOS doesn’t let you set app specific volume levels. Sound Control is a unique application that adds advanced audio controls to your Mac. Control the audio of each of your apps independently with per-app volume, EQ, balance, and audio routing.
Sound travels in waves, produced when an object — such as a stereo speaker — pushes on the air around it, causing small changes in air pressure. To describe sound waves, acoustic experts refer to concepts such as frequency and amplitude.

The Science of Sound
The frequency of the waves in the sound determines the sound wave’s pitch. Frequency is commonly measured in Hertz (Hz) with one Hz being equal to one wave completing a cycle per second. The human ear can detect a wide range of frequencies — from approximately 20 Hz to 20,000 Hz. Amplitude is a description of the sound wave's strength. As the amplitude of a sound wave increases, the volume of the sound increases. Music consists of a mixture of different frequencies and amplitudes.

The sound level heard by your ears is commonly measured in decibels. When referring to sound, a decibel is used to measure the amplitude of the sound wave. Decibels are useful in measuring sound because they can represent the enormous range of sound levels the human ear can hear using a more manageable scale. On the decibel scale, the softest sound that can be heard is 0 dB. Each increase of 10 dB represents an approximate doubling of the perceived loudness of the sound.
Sound and Your Ears
You can hear because your ears convert the vibrations of a sound wave in the air into signals that your brain interprets as sound. When the vibrations of a sound wave enter your ear, your eardrum and a set of tiny bones in your ear (the well-known hammer, anvil, and stirrup) amplify those vibrations. In your inner ear, these amplified vibrations move tiny hair cells that then convert the vibrations into nerve impulses sent to your brain. Your brain then interprets these nerve impulses as sound.
If you expose your ears to excessive sound pressure, you can harm those small hair cells in your ears. And if harmed, those hair cells can lose the ability to transmit sound to your brain. As a result, you could experience noise-induced hearing loss. Symptoms can include distorted or muffled sound or difficulty understanding speech.
While you can experience noise-induced hearing loss as a result of a one-time exposure to an extremely loud sound — like a gunshot — noise-induced hearing loss can also occur as a result of repeated exposure to loud sounds over time.
Listen Responsibly
Most research about noise-induced hearing loss has focused on prolonged exposure to loud sounds in industrial workplaces. While not as much research exists regarding the effect of recreational exposure to loud sound, if you listen to music and audio with headphones or earbuds — whether they’re connected to your iPod, your computer, or some other audio source — you should follow a few common-sense recommendations.
Think about the volume
There’s no single volume setting appropriate for everyone. You may experience a different sound level with different earbuds or headphones and with different EQ settings. Some hearing experts recommend that you set the volume while in a quiet environment, turn the volume down if you can’t hear people speaking near you, avoid turning up the volume to block out noisy surroundings, and limit the amount of time that you use earbuds or headphones at high volume.
Keep Track of Time
You should also pay attention to how long you listen to audio at high volume. Remember: you can adapt to higher volume settings over time, not realizing that the higher volume may be harmful to your hearing. Hearing experts warn that noise-induced hearing loss can also occur as a result of repeated exposure to loud sound over time. The louder the volume, the less time required before your hearing may be affected. If you experience ringing in your ears or hear muffled speech, stop listening and have your hearing checked.
If the sound on your Mac has stopped working, there are a number of 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
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. Install ipad apps on mac.
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. 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.
4. 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 High Sierra. If you’re not running High Sierra, 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 High Sierra, 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 you install either a new version of the OS or an update, backup your Mac using Time Machine, or whichever backup tool you normally use.
Screen record app mac. 5. Run Maintenance scrips
If you’ve determined your Mac’s sound definitely isn’t working, consider running CleanMyMac X’s 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).
Mac Sound Output Per Application
- Launch the app.
- Click Maintenance.
- Choose Run Maintenance Scripts and click Run.

How to check your sound settings
If you’re running the latest version of macOS and your sound still isn’t working, the next step is to check your Sound settings.
- Click on the Apple menu and choose System Preferences.
- Click on the Sound pane.
- Select the Output tab and choose Internal Speakers. If that’s not available as an option, contact Apple Support.
- Check if the volume slider is low, if so slide it to the right and check the sound again.
- Make sure the Mute box isn’t checked.
If, when you check your sound settings, you see a USB device selected rather than Internal Sound, 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.
- Go to System Preferences and choose Sound.
- Click on the Output tab.
- 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.
Switch app caroline leaf. CleanMyMac makes it very easy to completely uninstall any app so that it doesn’t leave any fragments or stray files behind. By using CleanMyMac, 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 for free here.
Restart the sound controller
If there are no software audio drivers interfering 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!
- Go to Applications>Utilities and double-click on Activity Monitor to launch it.
- In the search bar, type 'coreaudiod’ to locate the Core Audio controller.
- Click on coreaudiod, then click ‘X’ in the tool bar to quit it.
- Coreaudiod will restart.
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 a 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 recognise 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 sound.
The solution in that case is to plug the cable back in to the socket and remove it again. Try it a few times, if necessary, to ‘trip’ the sensor and make the Mac recognise 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.
Mac Sound Per App Free
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.
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.
- Go to System Preferences and click the Bluetooth pane.
- If it says Bluetooth turned off, turn it on.
Make sure your headphones or speakers are connected.
- Look in the list of devices in the main window to see if your headphones or speakers are listed.
- 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.
- 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 labelled Show Bluetooth in 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 labelled Show volume in 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. If that’s not possible, Apple will advise you on the best course of action to get your audio working again.
