Fix: High CPU Usage by RAVBg64.exe

Certain programs and applications run in the background all the time and you probably won’t even notice them until one of them starts misbehaving and begins to slow down your computer significantly. Background apps usually consume a very small amount of resources and they are not heavy on either the processing power or the memory. However, certain issues can occur where any application may begin to use abnormal amounts of RAM or CPU. The easiest way to keep track of this is by opening your Task Manager by clicking CTRL + ALT + DEL and selecting “Task Manager” among the option or by clicking CTRL + SHIFT + ESC.

What is RAVBg64.exe?

RAVBg64.exe is a process which belongs to the Realtek High Definition Audio codecs or the Realtek Driver. Either way, it is a process that runs in the background and it should not be terminated since Realtek HD Audio is a helpful tool that helps you manage audio on your PC. However, the process should not consume a lot of processing power or memory.

The process should be located in \Realtek\Audio\HDA folder and it’s usually in Program Files unless you set it otherwise. To check this, open your Task Manager, locate the RAVBg64.exe process, right-click on it and select “Open File Location”. This address should open up and there is a chance that the process is a virus if another location shows up. Let’s see how to address the issue at hand.

Solution 1: Update the Realtek Audio Driver

If you experience a constant high CPU usage by this process, you should first try to update the Realtek drivers. Drivers are the main components in communicating with Realtek hardware and your operating system. If they are somehow outdated or not compatible with the hardware, you will experience the high CPU usage. Make sure you are logged in as an administrator before proceeding.

  1. Press Windows Key and type Device Manager. Then in the search results, click on Device Manager.
    Device Manager in Windows Search Box
  2. Now expand the Sound, Video & Game Controllers section.
  3. Locate the Realtek Audio Driver.
  4. Right-click on it and select Update Driver.
    Update Audio Driver
  5. Restart your PC and check if the problem is solved.

Solution 2: Disable Realtek Audio Manager

Since it’s Realtek’s software that is causing the problem, you can always try to disable it from starting as soon as Windows turns on. There are two ways to do this.

  1. Locate the Realtek Audio Driver (follow steps 1 to 3 of Solution 1).
  2. Right-click on Realtek Audio Driver and select Disable device.

On the other hand, you can simply prevent the software from loading during startup without disabling it.

  1. If you are using Windows OS older than Windows 10, type “msconfig” in either the Search bar or the Run dialog box, and navigate to the “Startup” tab.
    Opening System Configuration through Run
  2. If you are using Windows 10, click CTRL + SHIFT + ESC to open Task Manager and navigate to the “Startup” tab.
  3. Uncheck the Realtek Audio Manager from starting and your CPU usage should go back to normal.

Solution 3: Add New Registry Values

This is perhaps the cleanest solution because it enables you to fix the issue without disabling the manager or possibly even leaving your PC without sound. It seems that the real issue with this background process consuming CPU power is the fact that it’s browsing the registry looking for several keys that have been deleted. Luckily, you can add those keys manually.

Warning: Proceed at your own risk as editing registry requires technical expertise and if done wrong, you may cause non-recoverable damage to your system.

  1. Type “Regedit” in the search bar and then in the search results, right-click on the Registry Editor. Then click on “Run as Administrator“.
    Open Registry Editor as Administrator
  2. In the Registry Editor, navigate to the
    HKEY_LOCAL_MACHINE/SOFTWARE
  3. Right-click on the Software folder and select New >> Key.
  4. Name the key “SRS Labs”.
  5. Now, right-click on the “SRS Labs” and select New >> Key.
  6. Name this key “APO”.
This is what the final result should look like

The high CPU usage should go down once you follow these steps carefully. Read the instructions thoroughly because creating a key in the wrong location definitely won’t do you any good.
