Internal speakers not working - Lenovo Yoga Slim 7 15ILL9 (83HM), Lunar Lake, CS35L56 left amp SPI probe failure

System Information

Field	Value
Machine	Lenovo Yoga Slim 7 15ILL9
DMI Product	83HM
BIOS	NYCN75WW (12/26/2025)
CPU	Intel Core Ultra (Lunar Lake)
Audio controller	Intel Lunar Lake-M HD Audio (00:1f.3, rev 10)
Audio chips	CS42L43 (SoundWire codec) + CS35L56 x2 (SPI amplifiers)
Kernel	6.18.13-200.fc43.x86_64
Distro	Fedora 43

Symptom

No internal speakers detected at all. aplay -l reports "no soundcards found". The right CS35L56 amp probes successfully but the left fails, preventing sof_sdw from registering the sound card entirely.

Bluetooth audio works. The issue persists across multiple distros (Fedora 43, Manjaro including kernel 6.12 LTS) and fresh installs, confirming this is not a userspace configuration issue.

Relationship to existing issue

This may be related to #5621 (HP Elitebook 8 G1i, same chipset). Both show identical left amp failure with HALO_STATE=0x0. However, this Lenovo has different ACPI errors (PMAP type mismatch returning Package instead of Buffer) which may indicate a distinct but related root cause.

Key errors

The left CS35L56 never communicates over SPI:

cs35l56 spi-cs35l56-left: Firmware boot timed out(0): HALO_STATE=0x0
cs35l56 spi-cs35l56-left: probe with driver cs35l56 failed with error -5

The right amp probes fine but lacks calibration data:

cs35l56 spi-cs35l56-right: Cirrus Logic CS35L56 Rev B0 OTP3 fw:3.4.4 (patched=0)
cs35l56 spi-cs35l56-right: No calibration for silicon ID 0x1da272567ba61

Sound card never registers:

platform sof_sdw: deferred probe pending: sof_sdw: snd_soc_register_card failed -517

ACPI PMAP errors at boot (repeated ~9 times):

ACPI Error: Incorrect return type from \_SB_.PC00.HDAS.IDA_.SNDW.SWD6.AF01.PMAP - received [Package], requested [Buffer]
ACPI: \_SB_.PC00.HDAS.IDA_.SNDW.SWD6.AF01: can't evaluate "PMAP" as buffer

@rfvirgil

@rfvirgil, can you take a look at this?

@drewbstew

@drewbstew Looks like you have several BIOS problems with that laptop. Also possibly your kernel is missing some bugfixes.

It is not related to #5621.

Can you please attach:

@drewbstew

@drewbstew Does sound work with Windows?

We've previously had confirmation that sound works correctly on this model with Linux:
thesofproject/sof#9720 (comment)

I have just updated the bios on my test system to
DMI: LENOVO 83HM/LNVNB161216, BIOS NYCN75WW 12/26/2025
and the audio drivers start up correctly with an updated Ubuntu 25.10 (6.17.0-14-generic) and also with a 7.0rc2 kernel.

@rfvirgil

Tested on 6.17.1-300.fc43.x86_64 — audio still not working, aplay -l reports no soundcards found.
dmesg errors are essentially identical to 6.18 (same PMAP type mismatch, same cs35l56-left firmware timeout, same sof_sdw -517).

@rfvirgil Regarding Windows: I only used Windows briefly during initial setup to update the BIOS, so I can't confirm audio state there. I believe audio was working on Fedora at some point shortly after setup, but I can't be certain — it's possible I'm confusing it with headphone use. I no longer have a Windows environment to test with.

Happy to provide any additional diagnostics that would help narrow down why your test system works with this BIOS but mine doesn't.

Found two Cirrus-related EFI variables:

CirrusSmartAmpCalibrationData
CirrusSmartCalInfo

The calibration data appears partial — only one amp has valid data, the left amp section is zeroed. This may explain why my unit differs from your test system. Could corrupted or incomplete EFI calibration data be preventing the left CS35L56 from initializing? Is there a way to reset or regenerate this calibration data without a working Windows environment?

@drewbstew

Hi @drewbstew,
The calibration data would come into play at a later point in time, the driver will still initialise the amplifiers without it.

At the moment there is a communication problem between the amplifiers and the codec - where @rfvirgil was asking whether Windows worked was a diagnostic as to whether it was a hardware issue.

The test system I have is a retail unit, I also had to reinstall windows on this to perform a bios update and to do that I needed to use the Lenovo pcsupport web site to generate recovery media

@simontrimmer

@simontrimmer I've done some more investigating on Windows and found that one of the three Cirrus Logic XU devices shows "requires further installation" in Device Manager. Running Get-PnpDevice on that device shows Service is blank and Manufacturer is Microsoft — meaning no Cirrus-specific driver is bound to it, just a generic Microsoft SoundWire class driver with no active service.
The device ID is SOUNDWIRE\SDCA_06&MAN_01FA&FUNC_4243&TYPE_01&VER_01&ADR_01&LID_00&UID_00&SUBSYS_380E17AA&DynamicEnumSpeaker0
Could you run the following on your working unit and share the output, specifically the Service and Manufacturer fields?

Get-PnpDevice -InstanceId (Get-PnpDevice | Where-Object {$_.FriendlyName -like "Cirrus"} | Select-Object -ExpandProperty InstanceId) | Format-List Name, Status, Problem, Service, Manufacturer

If your unit has a populated Service field where mine has blank, that would confirm the issue is a missing or non-matching driver binding rather than dead hardware.

If you're still running Ubuntu, could you run

ls -la /sys/bus/soundwire/devices/*/driver

or

sudo dmesg | grep -i "cs35l56|4243|spi-cs35l56"

and share the output?

Much thanks for the help.

Hi @drewbstew,
I'll include some debug from our system, but as this system has problems in both Windows and Linux it is more weight to a connectivity problem between the codec and the amps.

I have not been inside this laptop, but looking at some photos I suspect it may be a solution with the codec and the amps on different boards - might be worth getting a service centre involved to check that they are properly connected (or if it's new get it swapped).
