Intel Lunar Lake (ASUS Vivobook S5406SA): DSP panic creating drc.2.1, no audio at all

[arkybruh7]

Description

sof-audio-pci-intel-lnl can't bring up any PCM on this machine. Firmware boots fine, but creating the drc.2.1 module always fails with error 104, which panics the DSP and times out the IPC. Once that happens, every other pipeline fails too not just analog playback, capture and DMIC go down with it.

100% reproducible. Same failure happened 3 times in one boot's dmesg, on the first playback attempt each time.

Hardware

• ASUS Vivobook S 14 (S5406SA), Intel Lunar Lake-M
• Audio controller 8086:a828, codec ALC294
• Kernel driver: sof-audio-pci-intel-lnl

Software

• Ubuntu 25.10, kernel 6.17.0-40-generic
• firmware-sof-signed 2025.05.1-1ubuntu0.1 (SOF fw 2.14.1.1)
• Topology: sof-hda-generic-2ch.tplg

To Reproduce

1. Boot normally
2. Try to play anything through the internal speakers/headphones, or run:

   speaker-test -D hw:0,0 -c 2 -t wav
   

3. No sound. The failure shows up in dmesg immediately.

Expected behavior

drc.2.1 initializes successfully and analog playback works.

Actual behavior

drc.2.1 fails to initialize (error 104), which panics the DSP and times out the IPC. This cascades: pipeline.1 (analog playback), pipeline.4 (analog capture), pipeline.12 (DMIC), and pipeline.15 (deepbuffer analog) all subsequently fail
to build for the same reason. So this isn't a speakers-only bug — capture and DMIC are down too.

The exact same sequence repeats word-for-word at t=19.6s and t=271.8s in the same boot, so it's not a one-off race at driver probe it fails every single time something tries to open the analog pipeline.

Additional context

Let me know what else would help, I can pull a full alsa-info dump or a sof-logger trace if that narrows it down further.
