Windows 10: Intel Display Audio went missing after windows 10 automatic update

my system setup is:

CPU: i3 7100

Mobo: Asus Prime B250M-A

windows 10 1803

Windows automatic installed new intel display driver 25.20.100.6323


with HDMI connected to my AV receiver Yamaha RX-V677 then to my TV.

was using this setup for years without any problem, until today the windows decided to update and i lost the audio function.


I tried roll back the display driver, not working.


I tried to reset the PC (refresh), not working.


i tried download the driver from Intel and install manually, not working.


I had tried to reformat the windows, and it worked... for few minutes, but after windows automatically updated, the Intel Display Audio will went missing again and i lost the sound.


please advice what should i do and i dont want to format one more time.


thank you.

:)

 

Missing Intel Display Audio after 1809 upgrade


I have probably very similar, maybe exactly same problem. Intel HD stopped work after last W10 updates.

In computer is Intel i7-7500U (Intel HD Graphics 620), installed is W10 Pro 10.0.17134, Intel driver 25.20.100.6326

Before that, there was older version of this Intel driver, i tried remove device and detect it again, update driver trough Device Manager, update driver by "Intel Driver & Support" and tried some Intel utility. It updated driver for Bluetooth and WiFi, but not for audio and it still don't work after all that attempts.

There are no error messages in logfiles.

And that's all. Driver seems to be newest as possible but W10 still says "Cannot found any sound device", analog audio output is silent, HDMI audio doesn't work either. HD audio in device manager is detected, but Windows cannot use Intel driver for it and i don't know why.

 

Vista Automatic Updating Error

Automatic Updates isn't currently running.

 

No audio device is installed (How to fix?)


Since you uninstalled the Intel Display audio and you no longer have audio, that suggests you are using HDMI (??) If this is the case then the Realtek is not being used and not causing your problem.

First step as mentioned is to reinstall the Intel Display Audio.
