No sound from your computer? A quick troubleshooting guide
That moment of silence is never welcome. You are about to present in a critical video conference, or an employee needs to join a mandatory training webinar, and suddenly, there is no audio.
When you find there is no sound coming from your computer speakers, the cause can range from a simple unplugged cable to a complex driver conflict. This guide is designed for IT professionals and enterprise users who need to diagnose and solve audio issues effectively.

Start with the basics: Checking physical connections and volume
Before diving into complex software settings, it is essential to rule out the simplest physical issues. These oversights are surprisingly common and can be resolved in seconds.
Inspect all audio connections
Begin by inspecting all physical connections. Ensure that your speakers or headphones are securely plugged into the correct audio port on the computer. For USB devices, try a different USB port to rule out a faulty connection.
Verify power and volume settings
Next, verify that all external audio devices have power and are turned on. Many external speakers have a physical power switch and a volume knob. Check that the speaker system is powered on and that the volume is turned up to an audible level.
Check cable placement and integrity
If the speakers connect via a 3.5mm jack, ensure the cable is fully inserted into both the speaker and the computer. A partially connected cable is a frequent source of audio problems.
Test audio peripherals on another device
The issue could also be with the audio device itself. A simple but effective troubleshooting tip is to test the speakers or headphones with another device, such as a smartphone or a different computer. If you still hear no sound, you have successfully isolated the problem to the audio peripheral. If the speakers work with another device, the issue lies with the original computer's settings or hardware.
Leverage remote support for deeper checks
For IT teams, diagnosing these physical issues on a remote employee's machine can be a significant challenge. When you cannot be there in person, you need tools that allow you to take control of the software environment to rule out any non-hardware problems. This is where providing effective remote support becomes critical, allowing you to investigate software and system settings as if you were sitting right in front of the device, saving time and frustration for everyone involved.
Dive into software: Windows and macOS sound settings
If all physical connections are secure, the next step is to investigate the computer's software settings. An incorrect configuration within the operating system is one of the most common reasons for audio failure. Both Windows and macOS have centralized sound controls that can be inadvertently changed, leading to silence from your speakers.
Open sound settings in Windows
On a Windows computer, start by right-clicking the speaker icon in the taskbar and selecting "Open Sound settings." In the settings window, ensure the correct output device is selected under the "Output" section. It is possible the system has defaulted to a different device, like a monitor with no speakers or a disconnected Bluetooth headset. You can also run the built-in troubleshooter from this screen, which can automatically detect and fix common audio errors.
Use the classic Sound control panel
For a more detailed view, open the classic Sound control panel. You can find this by typing "Sound" into the search box on the taskbar and selecting the control panel result. In the "Playback" tab, you will see a list of all audio devices. Find your primary speakers or headphones, right-click, and ensure they are set as the "Default Device" and "Default Communication Device." You can also click "Test" to see if a sound is produced.
Check output settings on macOS
On macOS, the process is similar. Open "System Settings" (or "System Preferences" on older versions) and navigate to the "Sound" pane. Under the "Output" tab, you will see a list of available sound output devices. Make sure your intended speakers or headphones are selected.
Verify mute options and volume levels
Check that the "Mute" checkbox is not ticked and that the output volume slider is at an appropriate level. Sometimes, simply selecting a different output device and then switching back can resolve the issue.
Address driver issues: Updating or reinstalling your audio driver
When basic hardware and software checks do not solve the problem, the issue often lies with the audio driver. An audio driver is a specialized piece of software that allows your operating system to communicate with your computer's sound hardware. If this driver is outdated, corrupted, or incompatible, you will often find there is no sound coming from my computer speakers.
Update the audio driver in Windows
For Windows users, the primary tool for managing drivers is the Device Manager. To open it, type "Device Manager" in the taskbar search box. In the Device Manager window, expand the "Sound, video and game controllers" category. You will see your audio device listed, often with a name like "Realtek High Definition Audio" or "NVIDIA High Definition Audio." Right-click the device and select "Update driver" to have Windows search for a newer version.
Reinstall the audio driver for a clean fix
If updating the audio driver does not work, the next step is a clean reinstallation. In the Device Manager, right-click your audio device again and choose "Uninstall device." If a checkbox appears asking to "Delete the driver software for this device," check it to ensure a complete removal. After the device is uninstalled, restart your computer. Upon rebooting, Windows will automatically attempt to reinstall a fresh, default audio driver, which often resolves corruption-related issues.
Get manufacturer-optimized drivers
A valuable tip for IT professionals is to source the latest audio driver directly from the computer or motherboard manufacturer's support website. While Windows Update provides functional drivers, the manufacturer-specific versions are often better optimized for the hardware. This can solve persistent or obscure audio problems that the generic driver cannot. For macOS, audio drivers are integrated into the operating system, so ensuring you have the latest macOS update is the best way to keep them current.
Summary: Restoring your computer's audio
Troubleshooting a computer with no sound is a process of elimination. By working methodically from the simplest potential problems to the more complex, you can efficiently identify the source of the issue without wasting time. This structured approach begins with confirming physical connections and power, moves to verifying software settings within the operating system, and finally addresses potential audio driver conflicts.
Following these steps will resolve the vast majority of audio-related service tickets, restoring functionality and minimizing workplace disruption. Whether it is a muted volume slider, an incorrectly selected playback device, or a corrupted driver, the solution is typically straightforward once the cause is known. The key takeaway is to remain systematic and to test after each change to confirm if the problem has been resolved.
For persistent cases, using a secure remote desktop solution like TeamViewer enables IT teams to step in directly, diagnose the issue, and restore sound without requiring in-person support.
