Excessive CPU usage (25% continuous) from "Windows Audio Device Graph Isolation"

[dleff]

I too had the same problem and a new Spectre x360. The above solution almost worked. After doing the instructions, I had to remove the Realtek High Definition Audio (SST) a second time. This required a reboot, during which Windows installed the Realtek driver again - but an older version this time. Version 6.0.1.8351.

Thank you for posting back. 

Let's perform the following steps to isolate the issue and arrive at a fix:

Step 1: Run the sound problems troubleshooter

Automatically identify and fix audio errors with the Windows sound troubleshooting tool.

1. Right-click the notification area speaker icon , and then select Troubleshoot sound problems.

2. Select the device you want to troubleshoot, and then click Next to start the troubleshooter.

3. If a recommended action displays, select Apply this fix, and then test for sound.

Step 2: Check device and driver status in Device Manager

An outdated audio driver can cause sound errors and issues. Use Device Manager to check if the audio device is disabled, and then install an available driver update.

1. In Windows, search for and open Device Manager.

2. Double-click Sound, video and game controllers.

3. Right-click the audio device, and then select Update Driver.

4. Click Search automatically for updated driver software to check for and install a driver.

   

   • If an updated driver installs, restart the computer if prompted, and then test for sound.

   • If an updated driver is not available, continue to the next step to reinstall the existing driver.

5. Right-click the audio device again, and then select Uninstall to open the Uninstall Device window.

   

6. Select Delete the driver software for this device, and then click Uninstall.

   

7. In the top menu bar, click Action, and then select Scan for hardware changes to reinstall the device.

I had the same issue and downloaded and installed a previous version SP91516 and no issue anymore...hope that helps

There is definitely something wrong with the latest Realtek drivers for the HP Spectre x360. My CPU fan has been running constantly and I can see audiodg.exe using about 12-13% CPU all the time. Only after uninstalling the driver and letting Windows install an older one did the problem stop. HP...please fix the Realtek driver issues.

I'm facing the same problem.

The issued was solved by HP through remotely rolling back the RealTek driver to a previous version.

The current version (6.0.1.8437) is causing the problem of high CPU usage. Battery life then decreased from ~10 hours to ~6 hours.

When rolling back to the previous version, 6.0.1.8273, the high CPU usage was gone.

However, an automatic Windows Update re-installed the newest version (6.0.1.8437) and the problem resurfaced.

Instead of providing temporary solutions, the real solution would be to fix the RealTek driver.

Thought I found a workaround by rolling back to an older version...apparently not, got the same issue back now. So I upgraded to the latest driver and actually found out that if I do not start up Skype I don't have the issue. Once I start up Skype the issue is back.. After exiting Skype and restart the PC I got norml CPU usage again. So it seems it may have something to do with the Skype interface. Pls fix this issue.

Please note: You must restart immediately after removing the driver for this to work but I eventually got it sorted

This did not help me. It is still there. After the uninstall of all the audio drivers, it also asked me to restart windows. I did delete the files. It is all reinstalled but it seems Realtek's latest drivers are F**cked.
