[BUG] No internal speaker output on HP EliteBook 8 G1i (ALC245 + 2x CS35L54, SSID 103c:8d8f) — no HDA fixup matched

[guzgonav]

No internal speaker output on HP EliteBook 8 G1i (ALC245 + 2x CS35L54, SSID 103c:8d8f) — no HDA fixup matched

Summary

Internal speakers produce no sound at all on a HP EliteBook 8 G1i (Intel Core Ultra 7 268V, "Lunar Lake"). Headphones work correctly through the same codec. dmesg shows the codec finds no board-specific fixup for this subsystem ID and falls back to a generic 2-channel topology, which does not bring up the two external Cirrus Logic CS35L54 amplifiers that actually drive the speakers.

Hardware

• Laptop: HP EliteBook 8 G1i 14" Notebook AI PC
• CPU: Intel Core Ultra 7 268V (Lunar Lake)
• Codec: Realtek ALC245 (HDA codec Subsystem Id 103c:8d8f)
• Audio controller PCI Subsystem ID: 103c:8d8a (lspci: Intel Corporation Lunar Lake-M HD Audio Controller [8086:a828], subsystem Hewlett-Packard Company Device [103c:8d8a]) — note this differs slightly from the codec's own Subsystem Id register above; a fixup may need to key off either value
• Speaker amps: 2x Cirrus Logic CS35L54, attached via SPI (ACPI HID CSC3554)
• Audio controller: sof-audio-pci-intel-lnl 0000:00:1f.3
• BIOS version: X91 Ver. 01.05.02 (DMI Product Version SBKPFV3, Board Name 8D8A, System SKU D9FM3EC#ABE) — a different firmware family (X91) than the X70 BIOS on the two certified 255U/265H configurations of this chassis, consistent with this being a distinct board revision

Software

• Distro: Ubuntu 24.04.4 LTS
• Kernel: 7.0.0-31-generic (current HWE kernel — matches the kernel Ubuntu 26.04 LTS ships, so this is not a "kernel too old" case)
• SOF firmware: ADSPFW 2.14.1.1, loads and boots successfully
• Machine driver: skl_hda_dsp_generic
• Topology loaded: intel/sof-ipc4-tplg/sof-hda-generic-2ch.tplg (generic fallback — not model-specific)

Symptom

• No audio from internal speakers under any circumstance: silent via desktop apps, paplay, and speaker-test -D pulse. No click, pop, or glitch — total silence.
• Headphones via the 3.5mm jack (codec node 0x21) work correctly.
• alsamixer: Master and Speaker both unmuted, at 100/100. "Auto-Mute" control shows Disabled.

What's been ruled out

• Not a mute/volume issue — confirmed in alsamixer and in the raw codec dump (see Node 0x17 below): unmuted, output enabled, correctly routed.
• Not a PipeWire routing issue — tested with paplay and speaker-test -D pulse directly; still silent.
• Not a missing/outdated sof-firmware issue — firmware loads and boots without error (see dmesg).
• Not a kernel-age issue — already on kernel 7.0, the same major version Ubuntu 26.04 LTS ships. No older or newer stock Ubuntu kernel currently available changes this.
• Not a dead speaker pin — Node 0x17 is a real, wired pin (DefAssociation = 0x1), distinct from the several decoy Speaker at Ext Rear pins in the codec dump that all show the unconnected-template value DefAssociation = 0xf.

Root cause (as far as I can tell)

dmesg shows the amps are detected (Found 2 CSC3554 on spi) but the codec fixup match is blank for SSID 103c:8d8f:

snd_hda_codec_alc269 ehdaudio0D0: ALC245: picked fixup  for codec SSID 103c:8d8f

Node 0x17 (the real internal speaker pin) has no EAPD capability, unlike the headphone pin 0x21 which does — consistent with this board using the external smart-amp architecture (codec → SPI → CS35L54) rather than a simple EAPD-toggled speaker path. That architecture needs an explicit machine-driver/quirk entry to bind the amp component; without a matching SND_PCI_QUIRK entry for this SSID, that binding never happens, so the amps stay uninitialized even though the codec side is configured correctly.

Importantly, the driver stack for this amp family is already present and loaded on this system (confirmed via alsa-info.sh's loaded-module list): snd_hda_cirrus_scodec, snd_hda_scodec_component, snd_hda_scodec_cs35l56, snd_hda_scodec_cs35l56_spi, snd_soc_cs35l56_shared, snd_soc_cs_amp_lib. The CS35L54 shares its HDA-companion driver with the CS35L56/CS35L57 family, and that driver is loaded and idle. This doesn't look like it needs new driver work — it looks like it just needs a SND_PCI_QUIRK entry for this SSID that actually invokes the existing bind path.

This looks like the same class of issue as #5852 (HP Spectre x360, SSID 103c:8514, ALC285 + external amp, generic topology, no fixup matched, headphones-only) — just a different, newer board ID that hasn't been added yet.

Possibly related: #5663 reports the identical symptom on the same laptop family (HP EliteBook 8 G1i, Lunar Lake, ALC245) — but on the 16" chassis with Cirrus CS35L56 amps (ACPI HID CSC3556, SSID 103c:8e2c), rather than this 14" chassis with CS35L54 amps (CSC3554, SSID 103c:8d8f/103c:8d8a). That issue is tagged duplicate, suggesting there's a broader tracking thread for this laptop family that a maintainer can link this report to. The reporter there also tried model=alc245-hp-x360 and model=alc285-hp-amp overrides without success, for what it's worth.

Note node 0x17 has no EAPD bit at all, while 0x21 does — the working headphone path uses the codec's own EAPD-controlled amp; the non-working speaker path needs the external CS35L54 component driver bound instead, which requires a matching quirk.

/sys/bus/acpi/devices/CSC3554:00/status 	 15

(CSC3554 = the ACPI HID for the CS35L54 amps; status 15 = present, enabled, and functioning at the ACPI level — the amps themselves are healthy, it's purely the driver-side quirk binding that's missing.)

Request

Could a SND_PCI_QUIRK entry be added for 0x103c, 0x8d8f ("HP EliteBook 8 G1i") that binds the CS35L54 amp component driver, similar to the existing entries for other recent HP ALC245/ALC285 boards with external Cirrus amps? Happy to test a patch or build against this hardware.
