Windows Audio Device Graph Isolation affecting CPU performance

SteveC011 · ‎05-26-2016

Windows Update recently installed the IDT HD audio driver version 6.10.6491.0 on my laptop. I am now experiencing performance issues. Task Manager shows "Windows Audio Device Graph Isolation" taking an unusual amount of CPU. I have searched the issue online and taken several steps to attempt to resolve the issue. I reinstalled the previous driver with no difference. I unchecked "Exclusive Mode" on Speakers property page with no difference. I am using an HDMI external monitor with no speakers so I disabled the HDMI audio. I have run out of options.

Hi @SteveC011,

Thank you for visiting the HP Support Forums and Welcome.

I have looked into your issue about your HP ENVY 17-1011nr Notebook and issues with the sound since an upgrade. This link is from Microsoft and it should help fix the sound.

Please let me know how this goes.

I tried to uninstall the driver and restart. There was no improvement. Also no improvement for using the generic driver. One thing I failed to mention before is that I notice the performance lag when running the game, Lord of the Rings Online. I can't say it happens any other time but my other activities are not as performance sensitive.

Hey @SteveC01,

I know you should only have 1 driver option open to you and I feel that you should disable the other in your Device Manager.

This shows me that it is an old game. Seeing it only happens with this I would consult the On Line support.

Thanks.

I have gone back to the most recent driver as installed by Windows Update. This problem is not caused by a single application. It occurs with other software running.

Hi @SteveC011,

You could try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows. Please restart the Notebook twice to make sure all update have been completed!

Thanks.

The update completed a couple of weeks ago. I deleted the driver and reinstalled. I have restarted my notebook at least 6 times a day recently to do the installs and recommended troubleshooting. I have also been talking to Microsoft too and they have had me run System File Checker, System Maintenance Troubleshooter, and a Clean Boot.

After waiting for some kind of update or answer from HP for over three months, I did what I should have done three months ago and uninstalled Skype. The problem has gone away, I have no idea why but those annoying fans are not whirring all the time now. There is a perfectly acceptable web-browser based Skype and I now use that.

So, the answer seems to be - get the Skype Desktop app removed!
