It's been a while .. similar issue to my previous Lenovo P1 Gen 6 ..
now I've switched to Gen 9.
I couldn't get sound to work on P1 Gen 9. It worked fine on P1 Gen 6.
# lspci|grep audio
00:1f.3 Multimedia audio controller: Intel Corporation Panther Lake
Smart Sound Technology BUS
01:00.1 Audio device: NVIDIA Corporation GB206 High Definition Audio
Controller (rev a1)
Hardware
Machine: Lenovo ThinkPad P1 Gen 9 (model 21UFS0DJ00)
CPU/Platform: Intel Core Ultra Series 3 "Panther Lake"
Audio controller: Intel Panther Lake Smart Sound Technology BUS [8086:e328]
PCI subsystem ID: 17aa:235c (Lenovo)
Amplifiers: 2x Cirrus Logic CS35L57 Rev B2, OTP1, fw 4.2.1,
attached via SoundWire (SDCA SmartAmp function, type 1)
sdw:0:2:01fa:3557:01:0
sdw:0:2:01fa:3557:01:4
Also present on the SoundWire bus: SDCA SmartMic (type 3), UAJ
jack (type 6), HID (type 10)
Kernel
Mainline 7.3.0-rc1
sof-audio-pci-intel-ptl binds correctly to 0000:00:1f.3,
0000:00:02.0 (GPU/DSP)
SoundWire bus, Cadence controller, Intel bridge, and the CS35L57
SoundWire codec driver (snd_soc_cs35l56_sdw) all load and correctly
identify both amps by rev/fw version — driver-side recognition of the
codec is working
Failure
sof-audio-pci-intel-ptl 0000:00:1f.3: No SoundWire machine driver
found for the ACPI-reported configuration:
sof-audio-pci-intel-ptl 0000:00:1f.3: link 2 mfg_id 0x01fa part_id
0x3557 version 0x3
sof-audio-pci-intel-ptl 0000:00:1f.3: Use SoundWire default machine
driver with function topologies
sof-audio-pci-intel-ptl 0000:00:1f.3: SOF firmware and/or topology
file not found.
sof-audio-pci-intel-ptl 0000:00:1f.3: - ipc type 1 (Requested):
sof-audio-pci-intel-ptl 0000:00:1f.3: Firmware file:
intel/sof-ipc4/ptl/sof-ptl.ri
sof-audio-pci-intel-ptl 0000:00:1f.3: Topology file:
intel/sof-ipc4-tplg/sof-ptl-dummy.tplg
sof-audio-pci-intel-ptl 0000:00:1f.3: error: sof_probe_work failed err: -2
Neither file is present in the current sof-bin release tree.
Downstream of this failure, the SoundWire codec resume/read/write
attempts also start timing out (-110, -13) — believed to be a
consequence of the aborted probe, not a separate issue.
Result: no card registers with ALSA (/proc/asound/cards shows nothing
for the internal audio path).
What's confirmed working
Codec detection and identification (both CS35L57 amps enumerate
correctly with rev/fw info)
SDCA function enumeration (SmartAmp x2, SmartMic, UAJ, HID all
reported by ACPI)
Full kernel-side module chain: soundwire-bus, soundwire-cadence,
soundwire-intel, snd-soc-sdca, snd-soc-cs35l56-shared,
snd-soc-cs35l56-sdw, snd-sof, snd-sof-pci, snd-sof-pci-intel-ptl,
snd-soc-sof-sdw all present and loaded without error
What's missing
intel/sof-ipc4/ptl/sof-ptl.ri
intel/sof-ipc4-tplg/sof-ptl-dummy.tplg (or, more usefully, a real
topology matching this specific CS35L57 dual-amp SDCA configuration
rather than a dummy fallback)
Related prior reports
thesofproject/sof-bin#196 — ThinkPad P1 Gen 8 (Arrow Lake,
CS42L43+CS35L56), same "Dummy Output" symptom, missing
sof-arl-cs42l43-l2-2ch.tplg
Similar Panther Lake topology gaps reported independently for
other laptops (ASUS Zenbook S14, ASUS ROG Zephyrus G16) around the
same timeframe — suggests PTL+SDCA-amp topology coverage is broadly
behind hardware availability right now, not isolated to this one
board.
Happy to test candidate firmware/topology files and report back — full
module/dmesg trail available on request.
