Windows Audio Device Graph Isolation uses 20% of CPU

[GioRad]

The problem appears randomly, as soon as I plug my notebook for charging and when I unplug it, it still remains.

To solve it, at least temporarily, I have to manually kill the process (Windows Audio Device Graph Isolation) from Task Manager.

This issue is present since I updated to Windows 10 1809 October Update.

So far I have tried to update all audio drivers, install old drivers, uninstall all audio devices and reinstalling them but the problem still randolmly appears.

Unfortunately I had already done that and it didn't solve the issue, it still randomly appears. I figured that manually stopping the process works, it's not the best solution but for now I can live with that.

If I'll be able to figure out a definite solution I will post it here.

Me too.  This PC is up to date from HP Support.  

This problem seems easy to reproduce and HP should take it seriously.  This laptop has nothing unusual loaded on it and is used for straightforward simple Windows work.  It is wholly unbelievable that a PC from what should be a reliable company is showing this problem and it hasn't yet been fixed.  I understand that it is probably an issue of the audio device driver interacting with Windows components perhaps - but HP designed and decided on this hardware and has responsibility to get it fixed.

Using Tak Manager to kill the process is possible but is not a solution for non-technical users.

Happened again today, HP Support Assistant says all drivers are up to date, as well as BIOS (F07.A)

Thank you for posting back.
 

Try this step

Set BIOS default and restart:

1. Restart your notebook.
2. During startup, press F10 repeatedly until the BIOS menu is displayed.
3. Once the BIOS menu is displayed, press F9 to restore factory defaults.
4. Select Yes to confirm.
5. Press F10 to save changes and exit.
6. Select Yes to confirm.
7. The computer restarts using the default settings. If the issue persists continue next step:

BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

this should do the trick.

Hope this helps! Keep me posted for further assistance.

I tried the "BIOS default" method and up until now all is working fine. If in the next days the problem doesn't appear again I will mark the method as an Accepted Solution. If not, I'll let you know here.

Thanks for your help!

This method doesn't work, that process still uses up to 30% of the CPU.

If this problem has to do with drivers I don't know why HP is not able to fix it, this forum is filled with complaints about Windows Audio Device Graph Isolation.

Hi - could I ask that you post back what the solution turns out to be.  I think there are many people suffering this problem and the solution should be documented rather than all of us having to contact HP support individually.

Thanks!
