Restart your PC. Windows should automatically detect and reinstall the correct Intel(R) Trusted Platform Module driver upon reboot. Trusted Platform Module 2.0 Driver for BIOSTAR
Because Windows treats TPM 2.0 as an essential platform feature, there are no third-party standalone downloadable files for it. Instead, you must force the Windows Plug-and-Play (PnP) subsystem to rebuild the stack:
Here are the step-by-step methods to resolve this, ordered by likelihood of success. Method 1: Enable PTT/TPM in BIOS (Most Likely Fix)
This is the most revealing part. Historically, “AMP” in this context refers to , but in modern Windows 10 and 11 builds, it specifically relates to the Windows Audio and Power Management Proxy Device . The ID DEV-0101 is a unique identifier for a Microsoft-provided interface that helps manage audio streams during low-power states (like Modern Standby / S0 Low Power Idle).

is a virtual device that helps Windows manage audio playback and recording while your computer is in a low-power or connected standby mode. When the driver is missing, Windows doesn’t know how to handle audio power transitions, leading to the yellow bang in Device Manager.
On modern systems, there is no separate "standalone" driver to download; Windows manages it. To fix a yellow exclamation mark: Open .
The VEN-MSFT AMP-DEV-0101 device may use several methods to control the audio output, including:
: This identifier is the standardized "Plug and Play" hardware ID for a TPM 2.0 device. It acts as a secure cryptoprocessor that helps with generating, storing, and limiting the use of cryptographic keys. BitLocker Encryption : The driver associated with this ID is essential for BitLocker Drive Encryption Restart your PC
If it is already enabled, toggle it to , save and reboot, then return to the BIOS to re-enable it. This forces the ACPI table to rebuild itself. Press F10 to save changes and exit. 2. Clear and Reset the TPM Firmware
Every time the error appeared, a particular cubicle on the 7th floor would register a 0.3-degree Celsius temperature drop. Not the HVAC—a localized, impossible cold spot, centered exactly where Dr. Aris Thorne had sat before he "resigned" six months ago.
The ACPI VEN-MSFT AMP-DEV-0101 is a specific device identifier used in the Advanced Configuration and Power Interface (ACPI) specification. ACPI is a widely adopted standard for managing power and configuration in computer systems. The VEN-MSFT AMP-DEV-0101 identifier refers to a particular device that is used in modern computers, especially in the context of audio processing.
Click , then restart the computer. Windows will automatically parse the ACPI tables upon boot and build a clean driver stack linkage. Step 3: Apply the Relevant Chipset Framework Instead, you must force the Windows Plug-and-Play (PnP)
But when the world upgraded to the "Kingdom of Windows 11," Officer 0101 became the most important citizen in the city. The King decreed that no one could even enter the kingdom unless 0101 was active and standing guard.
Look for one of these terms depending on your processor type: AMD fTPM Trusted Computing / TPM Device Support Change the selection to Enabled .
: Windows utilizes an unmodifiable, native, built-in driver ( tpm.sys ) for this device. If updates corrupt the system file repository or trigger registry communication errors, a "protocol error between the driver and the device" will occur.
