Sound stops working after Windows 10 upgrade
Last Updated 7 years ago

The Windows 10 upgrade process makes every attempt to preserve all functionality that existed before the upgrade is completed. However, one of the system functions that seems to occasionally fall through the cracks is system sound...usually when the user is relying on the built-in PC speaker to provide the sound.

In order to fix this issue, download the most current driver available for the sound card on the manufacturer's website.  The most impacted systems seem to be the HP DC7900 models. There is a driver package available for this model on If you let the HP site detect the computer automatically, select Windows 7 Professional 64-bit (or 32-bit) as the Operating System and download the "HP Compaq dc7900 Desktop PC Integrated Device Drivers" package under the "Software - System Management" category. Decompress the files and use Windows Device Manager to update the audio drivers.

This is just an example of the fix employed for the DC7900 model specifically, but the overall process will be the same for other computer brands and models.
