"No effect when pressing F2"

No effect on pressing "F2" / Complete absence of audio signals.

This issue is usually being caused by antivirus programs such as: "Kaspersky", "Avast", "Dr.Web", "AntiMalwarebytes", and others. Disabling the antivirus does not help because the application isolates the cores at the PC startup. You need to find the program that isolated the cores; this could be anything from an antivirus and a crypto wallet to a NexusMods installer. Pay attention to any unusual running programs that may somehow affect on Windows Security.

1. Open the Core Isolation settings in Windows 10/11 (you can find it in the "Windows Security folder")

   
2. Disable the "Memory Integrity" feature in the "Core Isolation" tab

   
3. Completely uninstall any third-party antivirus software: "Kaspersky," "Avast," "Avira," "360 Total Security," "Dr.Web," "Avast", "Eset32".

4. Restart your PC and try again

Attention! If you have removed Windows Defender and cannot disable core isolation, please use a .bat file for automatic core isolation disablement.
