Realtek HD Audio Driver Version old post

Had some time since 8210 was out to look more into the Realtek Audio Manager missing issue. On Windows 10 x64 Home Edition with Creators Update. This is what I did:

1) In Windows, right clicked on Start Menu, Apps & Features, selected "Realtek High Definition Audio Driver" which shows as 6.0.1.8205 and clicked on uninstall.

2) Ran Remo Uninstaller's forced uninstall but nothing was found.

3) Rebooted system

4) After system reboot, went to Device Manager, then "sound, video and game controllers" where it listed Realtek High Definition Audio with the driver version 7571 which I think is what comes with Creators Update, update driver and pointed it to the 8210 folder with the browse for drivers. 8210 installed but the Realtek HD Audio Manager was not found in Control Panel or the Start Menu while C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe and C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe processes are running in the background. RAVCpl64.exe does exist in C:\Program Files\Realtek\Audio\HDA and I can run it which opens up Realtek HD Audio Manager.

5) Rebooted the system

6) Device Manager shows 8210 installed but the Realtek HD Audio Manager was not found in Control Panel or the Start Menu while C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe and C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe processes are running in the background.

Not sure what else I can do to fix this since I just have to manually run it using Windows Explorer and then select display icon in notification area. I remember in mid-late 2015 in this thread, I found a way to fix it but I can't seem to find my post to see exactly what I did.

 

System and compressed memory background process persistently consuming high CPU resources

Hi,

Thank you for posting in Microsoft Community.

Please answer these questions to get more clarity on this issue:

1. Did you make any changes to your computer prior to this issue?

2. Which anti-virus program is installed on the PC?

High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

Refer these steps:

• Press Windows key +X, select Control panel

• Change the view by option on the top right to Large icons
• Click on troubleshooting and click on the view all option on the left panel

• Run the System Maintenance troubleshooter

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

Thanks.

 

Realtek RAVBg64 running 4 times simultaneously

Other than saying others report this e.g.
Solved: Realtek HD Audio Background Process - Multiple Instances On Startup - Lenovo Community
multiple instances of ravbg64.exe - Microsoft Community

it's not yet clear to me why there may be several instances.

On my laptop I only have RAVCpl64.exe running.

(I've not reinstalled Win 10 since first installing build 1511, I think it was...)
