Updating your sound card driver
There’s also a really good chance that you have some onboard generic video card.Your best bet is to upgrade your video card drivers by heading to the manufacturer’s site, though you could just use the Upgrade driver feature built into Windows and explained below.However there is a simple fix from Bidness ETC that should solve it in just a few clicks.
This includes things like chipset, motherboard, sound card, and the like.
Step 4: Finally, click on Scan for hardware changes and the updated driver will be automatically installed. Your computer speakers should now be able to play sound normally.
If the sound is still not working, then try downloading and installing the latest sound card drivers for Windows 10 from the manufacturer's website.
For the most part, when you download drivers from somewhere like NVidia or AMD/ATI, they will have an entire driver installation wizard included in the download, so you’ll just run that to upgrade the drivers to the latest version.
If you happen to find a driver (perhaps for a device that is giving you an error) that is in a zip file, you can use the wizard screen above and choose the Browse option.
