80860f14 | Acpi

You will find this ACPI ID inside the following popular (and obscure) devices:

If you own any of these devices and run Linux, ACPI 80860F14 is likely the sole barrier to functional onboard audio.

The easiest way to resolve this is to let Intel detect the hardware automatically.

If you see this ID listed under "Other Devices" with a yellow icon, it means Windows does not have the specific driver installed to recognize or communicate with the Intel Serial IO hardware. Acpi 80860f14

This commonly happens after:

echo "i2c_designware_platform" | sudo tee -a /etc/modules

Most modern kernels (5.x and above) automatically handle this ACPI ID. You will find this ACPI ID inside the

ACPI 80860F14 is more than a cryptic hardware ID—it is the gateway to audio on a whole generation of Intel Atom SoCs. Its stubbornness on non-Windows platforms stems from incomplete ACPI BIOS implementations and the complexity of DSP-based audio routing.

Fortunately, the open-source community—specifically the Linux kernel and SOF teams—has made vast strides. With the right kernel modules, firmware files, and a bit of persistence, the mute can be lifted. For the average Windows user, it is a simple driver hunt. For the Linux enthusiast, it is a rite of passage into the world of ACPI debugging.

Next time you see ACPI 80860F14 in a log file, you will know exactly what it is: Intel’s Bay Trail audio DSP waiting for a proper handshake. And now, you know how to give it one. If you own any of these devices and
