Re: Windows Audio Device Graph Isolation


No, all the things are done on myself, then I probably need someone to help me look at the monitor.

It can certainly be turned back on. it might be worth doing this just to see if it will indeed affect the ram issue you are having. Can they remot into your computer?
I guess you don't use a braille display, so being without speech would be a problem.

Dell technical support insisted that I have to try disabling this, so how should I deal with it?

After disabling this, can this return to normal?

Hi William

Disabling this will unfortunately cause audio to stop on your system.

Can I ask which model Dell laptop you’re using?

The likely fix is to switch from the default Dell audio driver which I think is the Realtech Audio Driver, to the standard Microsoft driver, called HD Audio, by updating the driver.

You can do this from Control Panel > hardware and sound > Device manager > sound, video and game controllers (in the tree view).

Instead of searching for updates on the internet automatically, choose the manual option and select the button that will allow the user to choose a driver from a compatible list of drivers in the same category. Usually there will only be two drivers in this list, the current driver and the default MS driver HD Audio. This is the one you want. Just a note that your laptop will need to restart before using the new driver.

Hope that helps, let me know if you have any trouble.

Kind regards

I am not sure if disabling this will affect screen reader like nvda?
