Windows 10: Realtek HD Audio Causes Blue Screen APC_INDEX_MISMATCH

I have a Dell Inc. Inspiron 22-3263, i3 Processor, 6GB RAM. This all-in-one PC is approximately 4 years old. The PC has always run great, but a week ago it started blue screening with the APC_INDEX_MISMATCH moniker. I finally, narrowed it down to the Realtek Audio. If I disable the Realtek Audio, everything runs great. PC was running Windows 10 Home 1909.


To attempt to resolve easily, I decided to do a fresh install of Windows 10 Home. So, I am currently running a fresh install that has be updated to version 2004, with all updates current. I also went to Dell and updated to latest BIOS. None of which resolved the issue. If I enable the Realtek Audio, the system will blue screen as before. If I disable the audio, system will run perfectly. Does anyone have any recommendations.

Blue screen error: APC_INDEX_MISMATCH when trying to install Audio driver

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you get a Blue Screen error with “APC_INDEX_MISMATCH” when trying to install Audio drivers. I’ll certainly help you with this.



However, please let us know:

• Are you aware of any changes made to the computer recently?
  
• Which build version of Windows 10 are you using currently? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  
• What is the make and model of the computer?
  

An incompatible system driver causes the Blue screen error APC_INDEX_MISMATCH. For more information see

Bug Check 0x1: APC_INDEX_MISMATCH.



I would suggest you to refer the troubleshooting steps mentioned in the article

Troubleshoot blue screen errors and check if that helps.



However, I would also suggest you to share the dump files so that we can analyze them and get to the root cause of the issue. To share the files Navigate to
C:\Windows\Minidump, upload the files to OneDrive and share the OneDrive link.



Let us know the results.

Realtek Audio driver causing blue screen

I do have Realtek listed in Apps and Features before I uninstall to download and try a different version. I have been able to download the previous version of Realtek HD audio driver for pre RS3 Win10. This version of the driver doesn't cause BSOD but
instead gives me error 10. I've tried using the Audio Troubleshooter to diagnose from this point but the troubleshooter can't identify anything other than my Nvidia audio connected via HDMI. Hopefully contacting MSI will lead to an answer, thank you

 

Realtek Audio driver causing blue screen

So MSI's Realtek HD Universal driver is not installing, and causing BSOD ?

I assume Realtek audio is not listed in Programs and Features or
Settings>Apps and Features, but if it is you should uninstall

that driver as it's is likely corrupted. Reboot before trying to install the driver from MSI.

"Realtek audio control from the app store won't download and it seems to be a common problem for many users"

- Hmm, this may explain why the HD Universal driver is so small, but shouldn't have been a problem for many years, because this

universal driver thing only applies to newer hardware.

The traditional driver includes the Realtek HD Audio Manager program. No need to download anything from the Windows Store.

If you have not tried the full Realtek driver on the MSI download page you may want to give it a go anyway. The universal driver

is only recommended, so you may find the pre-universal driver still works properly.

If that installs successfully you could try installing the Universal package on top of the full driver if you find it is missing some options

in the Realtek HD Audio Manager.

- Because you are also having a problem updating the BIOS you may want to contact MSI support and forums.

The BSOD that happens only when the Realtek driver is installed could indicate a hardware fault in the Realtek audio chip or motherboard circuit.
