Re: Missing Cirrus CS35L56 firmware for Lenovo Xiaoxin Pro 14 ASP10 (SSID 17aa:3912) causes distorted/crackling audio

[Viktor Menshin <ripeeerr@gmail.com>]

Hi,

Follow-up to my earlier report, with a correction and a partial fix.

Correction: I initially assumed a Cirrus Logic smart amp (ACPI HID
CIRQ1080) was involved and that CS35L56 firmware was missing. That was
wrong - CIRQ1080 is actually a Cirrus touch controller (touchpad), not an
audio amplifier. There is no Cirrus amp ACPI device on this system at all
(no CSC3551/CSC3556 HID present). Sorry for the noise on that front.

What I've found instead: the codec falls back to the generic "17aa:0000"
Lenovo pin fixup (no entry for SSID 17aa:3912 in patch_realtek.c), and the
ALC287 vendor-specific processing coefficients (node 0x20) are left at
generic/uninitialized defaults. The Windows Realtek driver programs a
model-specific coefficient table into this node at init that the generic
Linux fallback never applies.

To find the actual values, I used VFIO passthrough to hand the physical
HD Audio controller (0000:c2:00.6, 1022:15e3) to a Windows 10 guest
running the stock Realtek driver, logged CORB verb traffic with a patched
QEMU, and extracted the SET_COEF_INDEX / SET_PROC_COEF sequence for node
0x20 using https://github.com/ryanprescott/realtek-verb-tools
(wiki: https://github.com/ryanprescott/realtek-verb-tools/wiki/How-to-sniff-verbs-from-a-Windows-sound-driver)

Headphones - fixed. A single coefficient write completely eliminates the
crackling/distortion on the headphone output:

  hda-verb /dev/snd/hwC1D0 0x20 SET_COEF_INDEX 0x36
  hda-verb /dev/snd/hwC1D0 0x20 SET_PROC_COEF 0x77d7

I've verified this is stable across reboots and under load.

Internal speakers - not fixed. I captured a much larger coefficient table
from a speaker-only session (headphones unplugged, 255 index/value pairs
on node 0x20, representing what looks like the driver's full cold-init
pass) and replayed it via hda-verb. This does not resolve the speaker
crackling.

Attached below:
1. Confirmed-working single coefficient write for headphones
2. The larger speaker-session table I tried, included for reference even
   though it doesn't fix the issue.

System info (unchanged from prior report): Lenovo Xiaoxin Pro 14 ASP10
(83LR), AMD Ryzen AI 9 365, ALC287 codec, SSID 17aa:3912, currently
running Linux 7.1.6-arch1-1.

Thanks,
Viktor Menshin
