In essence, when an ACPI device node has _HID set to PRP0001 , it tells the OS: "Don't look for a standard ACPI driver; instead, treat this device as if it were described by a Device Tree (DT) node. Look for a compatible string in my _DSD (Device Specific Data) properties."

It is primarily used in systems designed with both Linux/Coreboot and Windows compatibility in mind, where the BIOS provides a unified description of hardware. Common scenarios include: Chromebooks: Almost all modern Chromebooks use

: Manufacturers often use ACPI evaluation to toggle custom properties.

To fix this missing driver issue immediately, you must identify your device type and install its specific chipset or audio drivers. This comprehensive technical guide details what this ID means, why it appears, and how to resolve it across different hardware platforms. Understanding the ACPI\PRP0001\0 Hardware ID

When Linux scans, the official _HID ("TDA7802") becomes the primary identifier. However, if the driver does not yet contain an entry for "TDA7802" , the _CID fallback ensures the driver still binds via the DT compatible property.
