XPS 15 9570, (A7) Me FW Downgrade - Request MeSpilock failed and no audio output device installed

Hi,

Since the BIOS update to 1.16.2, my XPS has problems starting up.

After the Dell logo, the message "(A7) Me FW Downgrade - Request MeSpilock Failed" appears for 1-2 minutes and then he started normally. After logging in, the message "No audio output device installed" appears.

I have already searched for solutions, but nothing helps.

  • Downgrading the BIOS
  • Update the BIOS to 1.16.2
  • Intel chipset and Intel Management Engine components are updated

 

For the audio problem I tried to install the Realtek driver again. To do this, the current one need to be uninstalled and reboot. After the restart the new driver can be installed.

After the restart and before installing the Realtek driver, the audio output is working again and Realtek is not shown in Device Manager. After a few minutes, however, Realtek reappears in Device Manager and the audio output no longer works.

 

I hope someone can help me, thank you very much.

This video was right on point. This solve problem on xps 15 9570. Unlike other solution with device uninstall and reinstall driver, the step with update driver, browse my computer, Let me pick compatible HW, fixed the issue which Dell Support was setup to send MB replacement for. This issue is caused by software upgrades and must be more publicized .

I have not check for (A7) Me FW Downgrade - Request MeSpiLock failed issue yet

Thanks

@DELL-Cares After executing procedure described in the video, audio has been restored, but (A7) Me Fw Downgrade - Request MeSpiLock Failed. The issue with the POST message "(A7) Me Downgrade - Request MeSpiLock Failed" described on this forum and as I understand it might be fixed with enabling Safe Boot in BIOS, however this is not adequate solution and configuration with Safe Boot disabled must be supported, so could you please advise here or in a separate thread for "(A7) Me Downgrade - Request MeSpiLock Failed".

Hello, 

 

By default on the computer, secure boot should be on. Have you made any changes to the BIOS and require the secure boot to be off?

Hallo,

no i didn´t changed the BIOS, I just updated the BIOS with the Dell Update.

I found it as a solution for my Problem to switch Secure Boot to be off, and after a restart to be on again, but it didn´t worked.
