Audio speakers not working on HP EliteBook 8 G1i (Intel Lunar Lake) - ALC245 / CS35L56

[frododellacontea-hash]

Hello,

I am experiencing an issue where internal speakers are silent on my new HP EliteBook 8 G1i 16 inch (Next Gen AI PC). Headphones via 3.5mm jack work perfectly, but internal speakers remain silent despite being detected.

Hardware Details:

• Model: HP EliteBook 8 G1i 16 inch Notebook
• CPU: Intel Lunar Lake
• Audio Codec: Realtek ALC245
• Amplifiers: 2x Cirrus Logic CS35L56 (detected on SPI bus)
• OS: Fedora 43 (Forty Three) - Kernel 6.18.8
• Firmware: SOF firmware version 2.14.1.1

Symptoms:

• Headphones work.
• Speakers are detected but speaker_outs is reported as 0 in ALSA configuration.
• Tried kernel parameters like alc245-hp-x360 and alc285-hp-amp without success.

Alsa-info log: I have attached the full log, but the key IDs are:
Codec: Realtek ALC245
Subsystem Id: 0x103c8e2c
ACPI HID for Amps: CSC3556

Could you please help me identify if a specific quirk is needed for this model or if there is a missing topology file?

Thank you.

I suspect this is the same issue as: #5621

I checked dmesg for 'cs35l' and it returns no output, even though alsa-info detects CSC3556 devices. It seems the SOF driver is not even attempting to bind the Cirrus amplifiers.

It seems the SOF driver is not even attempting to bind the Cirrus amplifiers.

This laptop isn't SOF. It is HDA. It's the Realtek HDA driver that binds the amps.
The known issue on this laptop is that HDA driver cannot bind the amps because of an ACPI bug that prevents the SPI bus from probing the amp drivers.

Please install acpica-tools package and run this:

sudo acpidump >acpidump
acpixtract acpidump
iasl -d dsdt.dat
grep -B10 -A10 cs-gpios dsdt.dsl

And post the output of the grep here.

Here is the output of the grep command:

On my HP EliteBook 8 G11 (Lunar Lake), the SPI probe for CSC3556 fails with error -22.
spi_master spi0: error -EINVAL: failed to add SPI device CSC3556:00 from ACPI
Serial bus multi instantiate pseudo device driver CSC3556:00: probe failed with error -22
It seems like the ACPI tables for this SKU are not being parsed correctly by the current kernel 6.18 on Fedora 43.

@rfvirgil I have provided the grep output from the dsdt.dsl in my previous comment. It confirms the cs-gpios property is present but set to Zero.

I also tested the alc269-hp-gpio-led model quirk, but it didn't solve the issue. I still have to manually switch the output to 'Headphones' to get any sound, and internal speakers remain silent.

Please let me know the next steps to debug the SPI binding failure on this Lunar Lake machine.
