On my device manager, under "Other devices",

It says that the drivers for the Multimedia audio controller and video controller (VGA compatible) are not found.
At the same time, there is no sound on my computer even with the speakers on. I'm assuming it's because of the misssing audio controller drivers.

Does anyone know where I can find these drivers?

My computer is a ACPI Uniprocessor PC.

Any help will be greatly appreciated, Thanks.

Whether your sound card is integrated on the Motherboard, or it is a separate card, you need to look up the manufacturer and go to their site's support area for driver downloads. Drivers can get corrupted from time to time, and you should know where to go for driver updates.

There are also free and freemium apps available that can scan your computer and give you that information, some can even initiate the driver updates, although those usually are not free.
