    Windows Audio device Graph Isolation is making my cpu run hotter


    Just yesterday when i changed my pc case out, i noticed my fans spinning a lot faster than usual, i checked my windows task manager and noticed a "Windows Audio Device Graph Isolation" adding a 15% cpu load totaling 30% with all other processes. the result of this is a 120 degree F average temp, when it should really be (what im okay with) 90F.

    My audio is fine with out touching anything, end the process and i get no audio,*note when i did this i got a message from windows saying "no audio?" and went to their site and followed their instructions* upon reading some stuff i go into my device manager, the audio section, and i notice this new USB pnp Audio Device, which i never noticed (or was just blind) till now, uninstalled it and rebooted my PC, the device was still there +i had audio +the process wasn't running.

    Turned my PC on today and the Process is back and my temps are up.

    does anyone have a good way to remove the process permanently? also could it be the HD audio i connected to my motherboard from my front panel?

    While I don't have a direct answer to your direct question this article may shed some light on controlling.

    Well then you could shutdown the enhancements as outlined in article by entering your playback devices. Maybe not all but maybe one or two of them are driving the most activity. I believe you said you were okay with sound when you had killed this process so maybe you can shut all enhancements off.

    At least you know your options. Good luck.

    One thing I notice from your Device Manager is you only have "High Definition Audio Device" listed, apparently for the PC sound. That is only the generic, basic function, Windows installed sound driver. Get the correct hardware sound driver for your PC and see if that makes a difference. Any sound enhancements may need the correct driver for proper operation.

    HP shows an IDT driver for Win 8.1, which should work on Win 10 (no Win 10 drivers are shown).

    The USB PnP audio device. Do you have USB headset or mic plugged in?
