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.
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.
I was able to fix the Audio with this Video: https://www.youtube.com/watch?v=VQmRY4jxtoo
Thanks for linking the video that helped you, it fixed my audio as well. But have you fixed the original BIOS error issue or have you been living with it?
No I couldn´t find a solution for the BIOS.
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

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.
