80860f14 — Acpi

Most modern distributions (Ubuntu 20.04+, Fedora 34+, Arch Linux) include the necessary drivers, but they may need to be manually triggered.

Step 1: Identify Your Audio Codec Open a terminal and run:

sudo dmesg | grep -i "sst"
sudo i2cdetect -l (if i2c-tools installed)

Look for references to "byt" or "cht" and a codec ID like RT5640, RT5651, or ES8316.

Step 2: Load the Correct Machine Driver The machine driver tells the SST core how to talk to 80860F14. For most Bay Trail devices:

sudo modprobe snd_soc_sst_bytcr_rt5640

If that fails, try:

sudo modprobe snd_soc_sst_bytcr_rt5651
sudo modprobe snd_soc_sst_cht_bsw_rt5672

Step 3: Force ACPI ID Matching (Kernel Parameter) Add the following to your bootloader (GRUB) kernel command line:

snd_intel_sst.acpi_path=80860F14

Or for newer kernels using SOF (Sound Open Firmware):

sof_pci_debug=1

Step 4: Install Firmware (Critical for DSP) The SST DSP requires non-free firmware. Install the linux-firmware package, ensuring /lib/firmware/intel/ contains:

On Debian/Ubuntu: sudo apt install firmware-intel-sound Acpi 80860f14

Step 5: Blacklist Conflicting Drivers Sometimes the legacy snd_hda_intel grabs the PCI slot. Blacklist it in /etc/modprobe.d/blacklist.conf:

blacklist snd_hda_intel

After a reboot, aplay -l should show your analog audio device.

The mainline kernel does not have a native driver matching 80860F14 directly. Instead, it relies on:

Workarounds: Many device trees or kernel patches add explicit acpi_device_id entries: Most modern distributions (Ubuntu 20

static const struct acpi_device_id i2c_dw_acpi_ids[] = 
     "80860F14", 0 ,
     "PNP0D10", 0 ,
;

In Windows Device Manager, you may see an entry under “Other devices” labeled “Unknown device” with the Hardware ID ACPI 80860F14. No driver is loaded, and consequently, there is no audio.

No. The presence of ACPI\80860F14 in Device Manager does not indicate a broken component. It indicates a missing or corrupted driver. The physical I2C controller is integrated into the Intel SoC and is almost certainly functional.

If the driver package does not automatically install:
