Realtek Semiconductor Corp. - Extension - 6.0.9411.1 Install error - 0x80070103

This relates to a failed Win 11 update today. Whenever I click on retry, it fails to retry. I have been onto the Device Manager under "sound, video and Game controller" - Realtek (R) audio and looked at 'events'. There is a list of configurations and the final one states "device not started" with the following guidance

Device INTELAUDIO\FUNC_01&VEN_10EC&DEV_0274&SUBSYS_10280A06&REV_1000\5&d144696&0&0001 had a problem starting.

Driver Name: oem78.inf

Class Guid: {4d36e96c-e325-11ce-bfc1-08002be10318}

Service: IntcAzAudAddService

Lower Filters:

Upper Filters:

Problem: 0x0

Problem Status: 0xC00000E5 That means there are 2 problems 0x80070103 and 0xC00000E5

I've seen many queries on similar problems but no obvious solution. I've checked for errors on SFC/SCANNOW and DISM but can find none. I have disabled my anti virus. I can't delete the installation or roll it back as it hasn't installed.

I should add that the older driver works and when I try to update it I get the message that I have the latest driver; but it's not, is it? Otherwise why would Microsoft try and update it?

I've seen comments that as long as the existing driver works then one should ignore the failed update; so what is the point of the update then?

I want to solve this problem please for my own satisfaction and any help would be appreciated.

Hi Charlesdb,

I am Dave, I will help you with this.

Realtek supply PC manufacturers with a generic audio driver and some PC manufacturers customize the Realtek driver to suit their hardware, and if that is the case with your PC, then you should not install the Realtek driver provided by Windows updates, if it causes problems on your PC, there is no need to install that driver.

If that Realtek driver update is causing issues on your PC, you can use the Microsoft Show/Hide tool to hide the update:

I am seeing the same error. So I checked Device Manager to see what driver version is currently installed.

Device Manager > Sound, video and game controllers > Realtek Audio > Driver Tab

My driver version is 6.0.9034.1

Windows Update version is 6.0.8703.1.

Seems my driver is newer than Windows Update, which is probably why the update is failing.

Will take Dave's advice to hide this update.
