RAVBg64.exe (or ravbg64.exe) Process Is Causing High CPU Usage. How To Fix It?
It is normal for various different programs and processes to run in the system background and normally you would not even notice it, unless one of the programs or processes start to cause high CPU usage when it is not supposed to. If you are reading this, then most probably you have opened the Task Manager and noticed that a process called RAVBg64.exe (or ravbg64.exe) is causing way too high CPU usage and is slowing down your computer.
The RAVBg64.exe (or ravbg64.exe) background process is a part or Realtek software which allows users connect communication applications (like Skype) to Realtek sound controllers and ensures a proper communication between audio drivers and communication applications. You can notice this process to be a appearing not only in Task Manager, but in various notifications like a Skype notification which asks you to allow RAVBg64.exe (or ravbg64.exe) to use Skype application.
As you already know, it is a background process (and not some virus or malware infection) and it should not be terminated since it is a process which ensures a proper communication between audio drivers and communication applications. However, it should not cause high CPU (or memory) usage either. Still, many users reported that they encountered this high CPU usage caused by the RAVBg64.exe (or ravbg64.exe) process problem and wondered if it is possible to solve it. Good news is that it is actually possible and in this guide we are going to show you how.
In order to make the high CPU usage caused by this process you might need to update Realtek device drivers, disable Realtek HD Audio Manager and then enable it again, edit Windows Registry and to run the System File Checker. Read the guide below where you will find all methods described step by step, and see if the CPU usage gets back to normal after you apply them all.

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.
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.
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.
Disable Realtek Audio Manager
In this method we are going to show you how to disable Realtek Audio Manager from running at Windows system startup by using System Configuration and how to disable the audio device in the Device Manager. To prevent Realtek Audio Manager from running at the Windows startup, type "system configuration" in Search and click the "System Configuration" result.
In the System Configuration window, click on the "Startup" tab and find the Realtek software. Untick the checkbox near (or select it and click "Disable") it and click "Apply".
Then click "OK". You will be notified that you may need to restart your computer to apply these changes. Click the "Exit without restart" option.
Now go to Device Manager again, expand the "Sound, video and game controllers" section and right-click the Realtek device. Then select "Disable device" option.
Restart your computer and undo the changes by enabling Realtek Audio Manager to run at system startup and enabling the Realtek device in Device Manager. Your problem should be solved now and the RAVBg64.exe (or ravbg64.exe) process should not cause high CPU usage even after the next, and the next restart.
Create New Registry Keys
Windows Registry, usually referred to as just the registry, is a collection of databases of configuration settings in Microsoft Windows operating systems. It is used to store much of the information and settings for software programs, hardware devices, user preferences, operating system configurations, and much more. Many of the options exposed in the registry are not accessible elsewhere in Windows. To open Registry Editor you will need to open Run dialog box first. Press Windows Windows key + R or right-click Start and select "Run" and type "regedit". Press Enter or click "OK".
NOTE: Create a restore point before you make any changes in Windows Registry, editing Registry improperly may lead to more serious problems.
Now follow this path by expanding the keys: "HKEY_LOCAL_MACHINE/SOFTWARE". Right-click the "SOFTWARE" key, select "New" and then select "Key".
Name that key "SRS Labs". Then right-click the newly created key, select "New" and then select "Key" again. Name that key "APO".
The screenshot below shows how it should look when it is completed:
Close Registry Editor and restart your computer. See if the RAVBg64.exe (or ravbg64.exe) is still causing higher CPU usage than it normally should.
Run System File Checker
System File Checker is an utility in Windows which allows users to scan for corruptions in Windows system files and restore corrupted files. This guide describes how to run the System File Checker tool (SFC.exe) to scan your system files and to repair missing or corrupted system files. The "sfc scannow" option is one of the several specific switches available in the sfc command, in order to execute this command open Command Prompt as administrator. Type "command prompt" in Search, right-click the Command Prompt result and select "Run as administrator" option.
Now type the "sfc /scannow" command and press Enter. System File Checker will start and it should take some time to complete the scan. It should take about 15 minutes. Wait for the scanning process to complete, restart your computer and see if you are still having problems with the RAVBg64.exe (or ravbg64.exe) process.
That's it, we hope this guide was useful and you were able to solve the problem with the RAVBg64.exe (or ravbg64.exe) process using too much of the CPU.
