Windows Audio device graph isolation, skyrockets when I use feedback and type in it. In fact, it goes up to 25% when I type in the browser or feed back. What does audio have to do with typing?


This question is for MS SOFTWARE ENGINEERS, that are making are fans run for no reason and wearing out out laptops.


Why do I need audio device graph isolation running anyway? what purpose does it serve? Of course I will scour the web to find out my answer.

Windows Audio Device Graph Isolation HIGH CPU USAGE

My PC has a Realtek audio driver from Dell manufacturer with Waves maxx audio driver. Windows Audio Device Graph Isolation is using about 25% CPU usage. Enhancements tab is not appearing on playback properties. I want to disable enhancements to reduce
high CPU usage.

I don't want to install Microsoft's High Definition Audio Device for enhancements tab to appear. Is there any way to reduce high CPU usage while having the Realtek audio driver?

Windows Audio Device Graph Isolation using high CPU

I already tried
asking this in the HP Forum.

After the October update (version 1809) installed, this process has been using all of my CPU:

Windows Audio Device Graph Isolation

%winDir%\System32\audiodg.exe

I've taken several
troubleshooting steps:

• restarting
• virus scan
• Microsoft
  Safety Scanner
• check for new updates
• check for new drivers
• installing the
  driver again
• running
  DirectX Diagnostic Tool

I tried running the HP
Audio Check one click fix (version 1.0.1.8). It found "One or more audio service isn't running" and fixed them. However, the next time I restart, the process is using 100% of my CPU again. Same thing with the Windows Playing Audio troubleshooter.

There is a
Hotfix for previous versions of Windows, but not Windows 10. There are no conflicts in Device Manager. A YouTube video

() suggests removing all audio drivers and restarting, but that didn't help either.

Is there anything else I can try?

Thanks,

Shane.
