What You'll Learn
Check your volume settings
If your computer has lost sound, it can be incredibly frustrating, especially if you're in the middle of something important. Before you begin to panic, there are a few simple troubleshooting steps you can take to try and fix the issue.
First, check your volume settings. This may seem obvious, but it's often overlooked. If you're using a Windows laptop or PC, use the speaker keys on your keyboard to check if your volume is unmuted and turned up. If you don't have volume keys, click on the speaker icon in the bottom-right corner of your screen. Right-click the speaker icon and open the volume mixer settings to ensure none of the devices are muted. Also, check that the correct device is enabled under Sound settings.
If you're using a MacBook or iMac, head to the 'Control Centre' to check your system's volume settings. You'll find this icon in the top-right corner of your screen. Click on it to reveal an adjustable sound bar. Make sure the volume is turned up, and double-check that you haven't accidentally muted certain apps. Music and video streaming apps like Spotify, Apple Music, YouTube, and Netflix have their own volume controls, which can be muted by mistake.
If adjusting the volume settings doesn't work, there are other troubleshooting steps you can try, such as checking your cables and connections, updating your drivers, or restarting your computer.

Update your audio drivers
If you're having problems with your computer's audio, one solution is to update your audio drivers. Audio drivers are essential components that allow your operating system to communicate with audio hardware, such as a sound card or integrated audio controller.
Windows
To update your audio drivers on Windows, first open Device Manager. You can do this by pressing the Windows key + X and selecting "Device Manager" from the menu, or by typing "Device Manager" into the search box on the taskbar. Once Device Manager is open, locate and expand the category "Sound, video and game controllers" by selecting the arrow next to it. Right-click on your sound device (it may be labelled as "Realtek High Definition Audio", "Conexant SmartAudio", or something similar) and select "Update Driver". In the Update Driver Software window, you can choose to search for updated driver software automatically, or browse your computer for drivers. If you choose to search automatically, Windows will search for and install updated drivers if it finds them. If you choose to browse your computer, you will be able to select the audio device whose driver you want to update from a list of available drivers.
If you are still experiencing audio issues after updating your drivers, you can try uninstalling your audio driver. This will prompt your PC to reinstall your audio driver automatically. To do this, right-click on your sound device in Device Manager and select "Uninstall device". Make sure to select the "Attempt to remove the driver for this device" checkbox before selecting "Uninstall". After uninstalling, restart your PC.
If these solutions don't work, you can try using the generic audio driver that comes with Windows. To do this, follow the same steps as above to open Device Manager and locate the "Sound, video and game controllers" category. Right-click on your sound device and select "Update driver", then "Browse my computer for drivers", and finally "Let me pick from a list of available drivers on my computer". Select the audio device whose driver you want to update, then follow the instructions to install it. If this doesn't solve your audio issue, visit your device manufacturer's website and install the most recent audio/sound drivers for your device.
MacOS
To update your audio drivers on macOS, first check for updates by clicking the Apple menu in the top-left corner of the screen and choosing "About This Mac". In the window that appears, click on the "Software Update" button. This will open the App Store app and check for updates. If an update for macOS is available, click "Update" to install it. Sometimes, a sound driver update is bundled with a system update.
If you are still experiencing audio issues, you can try downloading and installing the latest audio drivers from the manufacturer's website. If compatible drivers are not available from the manufacturer, you may need to use the standard macOS audio drivers. In the Audio MIDI Setup app, select your Mac's speakers from the list of audio devices. Then, click the "Configure Selected Device" pop-up menu at the bottom of the sidebar and choose "Use This Device for Sound Output".

Check your connections
If you're experiencing audio issues with your computer, there are several troubleshooting steps you can take to resolve the problem. Here are some tips to help you check your connections:
Check your cables and connections: Ensure that your speakers or headphones are securely connected to your computer. Verify that all cables and cords are plugged into the correct jacks. Loose or faulty cables, disconnected speakers, or malfunctioning audio jacks can often be the culprit of audio issues. Make sure your speakers are also connected to a power source or fully charged if needed.
Check your volume settings: Confirm that your computer's volume is turned up and not muted. You can adjust the volume using the speaker keys on your keyboard or by clicking on the speaker icon on your screen. If you're using a Mac, you can check your system's volume settings by accessing the 'Control Centre' in the top-right corner of your screen.
Check your audio output device: If you have multiple audio devices connected, ensure that your computer is sending audio to the correct output device. This can be an issue if you've recently connected a USB headset, audio interface, or an external monitor without built-in speakers.
Check for hardware issues: If your speakers or headphones are securely connected and your volume settings are correct, the issue could be related to faulty hardware. This could include a faulty sound card, damaged audio jack, or malfunctioning speakers. In this case, you may need to consult a professional technician or consider replacing the hardware.
By following these steps to check your connections, you can often resolve common audio issues with your computer.
