Update Audio Drivers

Device driver is a software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly, if at all. Or some of the device's software processes could cause high CPU usage.

To update Realtek drivers open Device Manager by right-clicking the Start button and selecting "Device Manager" result from the contextual menu or type "device manager" in Search and click the "Device Manager" result.

update audio drivers step 1

In Device Manager you will see a list of devices connected to your computer. In this case you need to expand the "Sound, video and game controllers" section and right-click the Realtek device. Then select "Update driver" (or Update Driver Software...") option.

update audio drivers step 2

You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, then Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, then you will have to locate and install the drivers manually. Using this option requires having downloaded driver on your computer or USB flash drive and it is a longer process, because you will have to download all the latest drivers for all the devices manually by visiting the device manufacturer's official website. Select the option you prefer and follow the instructions. Once the updates are installed, restart your computer and see if the RAVBg64.exe (or ravbg64.exe) process is still causing high CPU usage.
