After updating chipset drivers, reboot and check Device Manager.
A recent system update failed to register the driver correctly.
: Device ID for the firmware-based TPM (Trusted Platform Module).
The VEN-MSFT AMP-DEV-0101 identifier is used to identify a device that is likely related to audio processing, specifically an audio amplifier or a device that controls audio output.
When this string appears in the Windows Device Manager alongside a yellow exclamation mark or is flagged as an "Unknown Device," it indicates that the operating system's kernel is unable to successfully initialize communication with the underlying motherboard security chip.
