What You'll Learn
Outdated or wrong sound driver
If your PC has no sound, it could be due to an outdated or incorrect sound driver. An outdated sound driver can cause hardware problems and prevent audio from working on your PC.
To fix this, you should first check if there are any Windows updates available. To do this, select 'Start > Settings > System > Sound'. Then, in the Output section, select the device you want to use for playback as your output device. If setting your audio device as the default device doesn't work, go to 'Start > Settings > Windows Update' and select 'Check for updates'. If updates are available, install them, restart your PC, and check if your sound is working.
If the issue persists, you may need to update your audio driver. To do this, go to the Device Manager by typing 'Device Manager' in the search box on the taskbar and selecting it from the results. Select the arrow next to 'Sound, video and game controllers' to expand it. Then, select your sound card or audio device, choose 'Update driver', and follow the instructions to install the updated driver. If you are unsure which driver to choose, select 'Browse my computer for drivers' and then 'Let me pick from a list of available drivers on my computer'.
If you are still experiencing audio issues, you can try uninstalling the current audio driver and letting Windows automatically reinstall it upon restarting your PC. To do this, right-click on your sound card or audio device in the Device Manager, select 'Uninstall device', and restart your PC. If this does not work, you can try using the generic audio driver that comes with Windows.
If none of these solutions work, you can visit your device manufacturer's website and install the most recent audio/sound drivers for your specific device model.

Faulty audio jack or speakers
If your PC has no sound, it could be due to a faulty audio jack or speakers. Here are some troubleshooting steps to identify and resolve the issue:
Check Connections and Volume Settings:
- Ensure that all cords and cables are securely plugged into the correct jacks or ports. Check for loose connections and try unplugging and replugging the cables, making sure they are firmly connected.
- Verify that the volume is not muted and that the volume level is set high enough to be audible. Check the volume settings on your PC, including any specific app volume controls.
- If you're using headphones with an AUX port (3.5mm jack), ensure they are plugged into the correct jack. Newer PCs may have a combo port for audio output and input, identified by a headset icon.
Select the Correct Output Device:
- Check your default audio output device by clicking on the speaker icon in the Windows taskbar. Select the correct output device from the list of available options.
- If you're using an external monitor, ensure it is not set as your default output device, as this could prevent audio playback.
Update or Reinstall Audio Drivers:
- Outdated or corrupted audio drivers can cause sound issues. Try updating your audio driver by visiting your PC manufacturer's website and downloading the latest driver. Then, restart your PC.
- If updating the driver doesn't help, try reinstalling the audio driver or using the generic audio driver that comes with Windows. You can do this by opening Device Manager, expanding "Sound, video and game controllers", right-clicking on your audio device, and selecting "Update driver" or "Uninstall device."
Test with Different Audio Devices:
- Connect different speakers or headphones to your PC to determine if the issue is with your original audio device or your PC's settings. If a new audio device works, it confirms a problem with the previous device.
- Try using Bluetooth headphones or speakers to see if the issue is specific to a particular type of connection.
Run Windows Troubleshooter:
Run the Windows Troubleshooter by clicking on the Windows "Start" button, searching for "Troubleshoot settings," and selecting "Run" next to "Audio." This will allow Windows to diagnose the issue and suggest potential fixes.
Perform a Repair Install:
If none of the above solutions work, consider performing a Repair Install by installing the Media Creation Tool and choosing "Upgrade Now." This will reinstall Windows while preserving your files, apps, and most settings.

Incorrect output settings
If your PC has no sound, incorrect output settings could be the culprit. Here are some troubleshooting steps you can try to address this issue:
Check Default Audio Devices
Firstly, ensure that the correct output device is selected as the default. To do this, click on the speaker icon on the Windows taskbar, typically found in the bottom right corner. From the list of devices that appears, select the device you want to use for playback as your output device. You can also access the sound settings by going to Start > Settings > System > Sound. In the Output section, choose your device, and if needed, scroll down to find and select "More volume settings." Here, you can set your chosen device as the default for audio playback.
Run the Windows Troubleshooter
If setting the correct default device doesn't solve the issue, run the Windows Troubleshooter. Go to Start, search for "Troubleshoot settings," and select "Other troubleshooters." Click "Run" next to "Audio" and let Windows diagnose and suggest fixes for your audio issue.
Update Audio Drivers
If the issue persists, the problem could be related to outdated or incorrect audio drivers. Update your audio drivers by going to the device manufacturer's website and downloading and installing the latest audio driver for your specific device. For Dell computers, you can visit Dell.com/Support to identify and download the necessary driver.
Adjust HDMI Settings
If you're using an HDMI connection, try disabling HDCP (High-Bandwidth Digital Content Protection). This setting can sometimes interfere with sound output.
Disable Audio Enhancements
In some cases, audio enhancements can cause sound issues. To disable them, go to your sound settings, select your device, and then scroll down to find "Advanced settings." Look for the Audio enhancements option and switch it off using the dropdown menu.
By following these steps, you should be able to address any incorrect output settings that may be causing your PC audio issues.

Headphones plugged in
If your PC has no sound even when headphones are plugged in, there could be several reasons for this. Here are some troubleshooting steps you can try to resolve the issue:
Check Connections and Volume Settings:
- Ensure that your headphones are securely plugged into the correct audio jack or USB port. Some PCs have separate audio-out and mic jacks, while others have a single combo port for both audio output and input. Make sure your headphones are plugged into the correct jack.
- Check that the volume on your PC and headphones is turned up and not muted. Some speakers and apps have their own volume controls, so verify that the volume is set to an audible level in all relevant places.
Select the Correct Audio Device:
If you have multiple audio devices connected to your PC, make sure that the correct output device is selected. On Windows, click on the speaker icon in the taskbar, then select the audio device you want to use from the list.
Update or Reinstall Audio Drivers:
Outdated or corrupted audio drivers can cause sound issues. Try updating your audio driver by right-clicking on the driver in Device Manager and selecting "Update driver." If that doesn't work, try reinstalling the driver by uninstalling it and then scanning for hardware changes.
Run the Audio Troubleshooter:
Windows has a built-in audio troubleshooter that can help diagnose and fix common sound issues. Run the troubleshooter and follow the on-screen instructions.
Check for Hardware Issues:
Inspect the headphone cable and connector for any damage, kinks, or frays, as this can disrupt the audio signal. Try plugging your headphones into a different device to see if they work.
Bluetooth Connection Issues:
If you're using Bluetooth headphones, ensure that your computer is successfully connected to the headphones. Check the Bluetooth settings on your PC and make sure the headphones are listed as "Connected."
If none of these steps resolve the issue, you may need to consult a professional technician to diagnose and fix more complex problems, such as hardware failures or driver conflicts.
