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 which runs in the background and it should not be terminated since Realtek HD Audio is a helpful tool which 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. In order 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: Updating the Realtek Driver

If you experience a constant high CPU usage by this process, you should firstly try to update the Realtek drivers.

  1. Open your Device Manager and go to the Sound, Video & Game Controllers section.
  2. Locate the Realtek Audio Driver.
  3. Right-click on it and select Update Driver.
  4. Restart your PC.

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 days to do this.

  1. Locate the Realtek Audio Driver like in the Solution 1
  2. 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.
  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: Adding 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 which have been deleted. Luckily, you can add those keys manually.

  1. Type “regedit” in the Search bar and click on the only result.
  2. Visit this location: “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.
