apport information
** Tags added: apport-collected resolute wayland-session
** Description changed:
== Environment ==
Ubuntu version: 26.04 LTS
Kernel: 7.0.0-10110oem
Machine: Lenovo Yoga Pro 9 16IPH11 (BIOS product name: 83SF)
CPU: Intel Panther Lake (Core Ultra Series 3)
GPU: NVIDIA GB206 (discrete)
Audio hardware: Intel Panther Lake Smart Sound Technology (00:1f.3)
+ NVIDIA GB206 HDA (02:00.1)
== Problem ==
Internal speakers and microphone are not detected. Only HDMI audio
outputs (from the NVIDIA card and SOF HDMI passthrough) are available.
The sound settings dropdown shows only "Dummy Output" / "Dummy
Microphone" for internal audio.
== Root cause (from kernel log) ==
The SOF driver (sof-audio-pci-intel-ptl) loads and detects SoundWire
devices on links 0 and 3, but reports:
"No SoundWire machine driver found for the ACPI-reported configuration"
"part id 0x105 is not supported"
It then falls back to the generic HDA machine driver
(skl_hda_dsp_generic) with topology sof-hda-generic-idisp-4ch.tplg,
which only exposes HDMI outputs — not the internal codec.
The SoundWire devices detected are:
link 0: mfg_id 0x01fa part_id 0x3556 version 0x3 (×4 entries)
link 0: mfg_id 0xd010 part_id 0x0105 version 0x0 (unsupported)
link 3: mfg_id 0x01fa part_id 0x4243 version 0x3
link 3: mfg_id 0x025d part_id 0x0722 version 0x3
This machine's SoundWire codec combination is not present in the
sof_sdw machine driver's quirk/match table.
Additionally, intel_quicki2c (00:10.0) produces continuous
"unexpected DIR happen" errors during operation, and reports
"Can't find wake GPIO resource" at boot — this appears to be a
separate driver issue with the touchscreen I2C controller on this
platform, but is noted here as it may be related to Panther Lake
enablement status.
== aplay -l output ==
Only HDMI devices are listed (NVidia card 0, SOF HDMI passthrough
card 1 devices 3/4/5). No Speaker or Headphones device appears on
card 1 as would be expected if the SoundWire codec were initialised.
== Steps to reproduce ==
1. Boot Ubuntu 26.04 with kernel 7.0.0-10110oem on a Lenovo Yoga
Pro 9 16IPH11 (model 83SF).
2. Open Settings → Sound.
3. Observe that no internal output or input device is available.
== Expected result ==
Internal speakers and microphone are detected and functional.
== Actual result ==
Only HDMI audio outputs available. Internal audio completely absent.
== Workaround ==
None known. Bluetooth audio works.
== Request ==
A DMI/SoundWire quirk entry needs to be added to the sof_sdw machine
driver (sound/soc/intel/boards/sof_sdw.c or equivalent) for this
machine and codec combination, matching on:
System product: 83SF (or "Yoga Pro 9 16IPH11")
SoundWire IDs as listed above
Similar prior art: commit 85743a847cae (ALC287_FIXUP_YOGA7_14ITL_SPEAKERS)
and the Lenovo Yoga Slim 7 Ultra 14IPH11 SoundWire quirks.
