Computers use sound cards to send sound signals from your computer to your speakers. A sound card is a piece of hardware inside the computer that can be built into the motherboard or a standalone card. Most modern computers use high-quality audio hardware integrated directly into the motherboard. If you are adding a dedicated internal card, it will likely use a PCIe (PCI Express) slot. Additionally, external USB sound cards and Audio Interfaces have become incredibly popular for gamers and content creators who need professional-grade inputs and outputs.
These sound cards use drivers to communicate with the operating system. For most users the operating system is some version of Microsoft Windows. Of course there are other operating systems such as macOS and Linux. In Windows 10 and 11, the system is much more proactive. When you connect new audio hardware, Windows Update usually fetches the driver in the background automatically. However, for specialized cards, you should still visit the manufacturer’s site for the full software suite to unlock features like spatial audio or advanced EQ settings.
There are a few ways to install drivers for your sound card. The most common way is to install the driver/software for your sound card or motherboard if its onboard audio. Sometimes you will install the software before the card and sometimes you will install the card before the software depending on the manufactures instructions. The software contains the drivers and any other sound management utilities such as a mixer for example. Windows also has a way for you to manage your sound settings.
If you don’t have the software that came with your sound card you can usually download it from the manufactures website if you know the model of the sound card. Another way to install drivers is from Windows update. This will only work if Windows recognizes your card and knows what drivers to look for. Sometimes if you restart your computer Windows will see that you have new hardware and ask you how you want to install the software for it. There will be a section asking you if you will allow Windows to go to search for drivers online and see if it can download the correct driver.
You can also go into Device Manager and find the sound card and double click it to open its properties. Then go to the Driver tab and click on update driver and follow the prompts to have it search your computer or Windows update. If you don’t see your sound card, check the “Other devices” section for an “Unknown Device” with a yellow warning triangle. This indicates that the hardware is detected but the driver is missing or incompatible. This is a common issue after a major Windows Update or a fresh OS installation. This is a good place to look if you are having sound problems with an existing sound card that came with your computer. The driver could have become corrupt or you may have inadvertently downloaded a new driver during Windows Update that is causing a conflict. There is a button to roll back the driver to go back to the previous version which may solve your problem. You can also remove the device from Device Manager, reboot the computer and let Windows detect the sound card again and reinstall the drivers.
If you are having problems with an existing sound card not working all of the sudden and everything looks fine in Device Manager then the next step is to check your speakers and speaker connection. If you have a different headset or a smartphone with a 3.5mm jack, plug your speakers into that to see if they produce sound. This helps determine if the failure is in the speakers themselves or the PC hardware. If so then your speakers are most likely not good anymore. Also make sure they are plugged into the right jack and that the plug is in all the way.
Next make sure your volume is turned up. Some speakers have separate volume controls on the speakers themselves that can be used in addition to the volume control within Windows. In Windows 11, the volume icon is part of the Quick Settings cluster in the bottom right. If it’s missing, it is usually hidden in the taskbar overflow menu (the upward arrow). To manage this, right-click the Taskbar, select “Taskbar settings,” and ensure the sound icon is toggled to appear in the system tray.
The Modern Windows Sound Settings
In modern Windows versions, troubleshooting is handled in the Settings app rather than the old Control Panel:
- Go to Settings > System > Sound.
- Output: Ensure the correct device (Speakers, Headphones, or Monitor) is selected as the default.
- Volume Mixer: Scroll down to the “Advanced” section to ensure individual apps aren’t muted.
- Troubleshoot: Click on “Output devices” under the “Troubleshoot” section to let Windows automatically reset the audio service and check for muted channels.
If you are using a dedicated PCIe card, you can try “reseating” it by taking it out and putting it back in firmly. If you’ve added a new card and are getting no sound, you may need to enter the BIOS/UEFI and disable the “Onboard Audio” to prevent conflicts between the motherboard chip and your new card. If your sound card is built into the motherboard then this is not an option although you can add an actual sound card and use that instead of the built in sound card. Finally it is possible that the sound card or speaker jack on the card has gone bad and you may end up having to replace it with a new one.
