[BUG] X1 Carbon Gen 13 (LNL, RT713/RT1318, DMICs present): widget drc.100.1 fails IPC load (UUID B36EE4DA-...) — distinct from fixed #10401 (no-DMIC variant)

[wee-beybrice]

Audio fails to initialize on the X1 Carbon Gen 13 (Lunar Lake) with current sof-firmware: no ALSA cards register, no playback or capture available. Reproduces 100% across reboots and across multiple kernel versions (Linux 7.0.3, 7.0.4, mainline torvalds/linux master) — not a recent regression.

Hardware

ThinkPad X1 Carbon Gen 13 (Lunar Lake), SoundWire — RT713-SDCA on link 0, RT1318 on link 1.

Software

• sof-bin v2025.12.2
• Linux 7.0.4 (also seen on 7.0.3 with identical dmesg signature)
• Also reproduced against torvalds/linux master (2026-05-08), where include/uapi/sound/sof/abi.h defines:

#define SOF_ABI_MAJOR 3
#define SOF_ABI_MINOR 23
#define SOF_ABI_PATCH 1

Distinct from #10401 — same hardware, opposite NHLT variant

NHLT here reports DMICs detected in NHLT tables: 2 (vs 0 in #10401), so the DMIC DAI binding succeeds; the failure shifts to widget drc.100.1 (UUID B36EE4DA-006F-47F9-A06D-FECBE2D8B6CE). #10410's no-DMIC topology variant does not apply to this variant.

Filing per kv2019i's "Please file a new bug if some issues remain" close note on #10401.

Symptom

snd_soc_register_card fails with -22 (-EINVAL); cat /proc/asound/cards returns --- no soundcards ---.

sof_sdw sof_sdw: error -EINVAL: snd_soc_register_card failed -22

The relevant chain in that trace: topology load is initiated, the Topology: ABI 3:29:1 Kernel ABI 3:23:1 line is logged informationally and the kernel proceeds; the kernel then issues IPC4 message 0x19000000 to instantiate widget drc.100.1 on the DSP; the DSP returns -19 (-ENODEV); topology load aborts with -22 and sof_sdw never registers a card.

Workaround

Replacing four LNL-specific file groups under /lib/firmware/intel/ with the v2024.09.1 set restores audio after reboot, including the 3.5mm jack on RT713-SDCA. ADSPFW (the boot firmware running on the DSP) downgrades from 2.14.1.1 to 2.13.0.1 as a side effect; firmware files for other platforms are untouched.

The widget binary itself (/lib/firmware/intel/sof-ipc4-lib/lnl/B36EE4DA-006F-47F9-A06D-FECBE2D8B6CE.bin) is on disk and identical-size in both firmware sets, so this isn't a missing-file-on-disk issue — the file is loadable, but the IPC instantiation request to the DSP returns -ENODEV.

@wee-beybrice Ok. The DRC DSP module was moved to from base module into separate module in v2025.12. The expected behaviour is that kernel will try to load the firmware from /lib/firmware, but for some reason this is not happening in your case. Can you rename sof-dyndbg.conf.txt to sof-dyndbg.conf and put it in the /etc/modprobe.d/ folder, and get the dmesg log after reboot? The kernel driver will print messages when it attempts to load the module.

[wee-beybrice]

Thanks for the quick response. Re-applied the stock v2025.12.2 firmware files to /lib/firmware/intel/ (boot firmware, library, topology) and installed your sof-dyndbg.conf into /etc/modprobe.d/. dmesg below, captured via sudo dmesg -T | grep -iE 'sof|snd_|soundwire|asoc|sdw|codec|dsp|audio|firmware:|iwlmld'.

One artifact to flag: the initramfs (/boot/initramfs-7.0.5-wee-bey.img) was generated while my local audio workaround had v2024.09.1 firmware installed, so it has the older ADSPFW 2.11.1.1 boot firmware embedded. The log shows that loading first (pre-pivot), then ADSPFW 2.14.1.1 reloading from /lib/firmware after pivot. The drc.100.1 failure happens after the 2.14.1.1 reload, so I don't think the mismatch is masking anything — but happy to regenerate the initramfs against current /lib/firmware and re-capture if it would help.

What's notably absent from the log (re: your "for some reason this is not happening" hypothesis): no firmware: request line for B36EE4DA-006F-47F9-A06D-FECBE2D8B6CE.bin (or any other UUID-named .bin from /lib/firmware/intel/sof-ipc4-lib/lnl/). The kernel does not appear to attempt to fetch the DSP module's .bin before the IPC for drc.100.1 fails. The widget binary IS on disk: /lib/firmware/intel/sof-ipc4-lib/lnl/B36EE4DA-006F-47F9-A06D-FECBE2D8B6CE.bin (size 0xb720, identical between v2024.09.1 and v2025.12.2 firmware sets).

Dyndbg activated for ~85 modules per /sys/kernel/debug/dynamic_debug/control post-boot.
