[BUG] Lenovo Yoga Pro 7 15IPH11 (Panther Lake): sof_sdw probe fails with -EEXIST on duplicate SDW3-Playback-SimpleJack — RT721 + RT1320 + RT722 on link 3

[yurtsevich]

Describe the bug

On a Lenovo Yoga Pro 7 15IPH11 (Intel Core Ultra 7 356H, Panther Lake), no ALSA
card is registered for the internal audio. The only playback device available is
HDMI audio from the discrete NVIDIA GPU, so internal speakers, the 3.5 mm combo
jack and the internal DMIC array are all unusable.

Two distinct failures are visible in the kernel log:

1. The machine driver table has no entry matching the ACPI-reported SoundWire
   configuration of this board — three Realtek devices on link 3:
   RT721 (0x0721), RT1320 (0x1320) and RT722 (0x0722). The driver falls back to
   "SoundWire default machine driver with function topologies".

2. In that generic path, the card fails to register because two DAI links are
   given the same name. Both RT721 and RT722 expose a jack function on link 3, so
   both attempt to register SDW3-Playback-SimpleJack, and the second
   kobject_add_internal returns -EEXIST. mc_probe then aborts and
   sof_sdw probe fails with -12.

SOF firmware itself boots normally (ADSPFW 2.14.1.1), so this is a machine
driver / DAI-link naming issue rather than a firmware loading problem.

What I have tried:

• Verified PipeWire/WirePlumber 1.6.2 are running correctly; they simply have no
  non-HDMI sink to expose. aplay -l shows only the NVIDIA HDA HDMI codec.
• Reinstalled firmware-sof-signed; no change — firmware loads and boots fine.
• Confirmed the failure is independent of the desktop environment (reproduced in
  both GNOME and KDE Plasma sessions).
• Confirmed this is not a mixer/mute issue: no sofsoundwire card exists at the
  ALSA level at all.

Possibly related:

• [BUG] Lenovo Yoga Pro 9 16IPH11- No SoundWire machine driver found: part id 0x105 is not supported linux#5881 — Lenovo Yoga Pro 9 16IPH11, same product generation,
  also "No SoundWire machine driver found", though with a different part_id set.
• [BUG] No audio on ASUS Zenbook Duo UX8407AA (2026) (Panther Lake Intel X9 388H) — regression between 7.0.11 and 7.1.2, RT722 SoundWire probe failure CachyOS/linux-cachyos#908 — ASUS Zenbook Duo UX8407AA, identical
  SDW3-Playback-SimpleJack duplicate-name signature and the same
  probe with driver sof_sdw failed with error -12. That report describes it as
  a regression between 7.0.11 and 7.1.2.

To Reproduce

1. Boot Ubuntu 26.04 LTS (kernel 7.0.0-31-generic) on a Lenovo Yoga Pro 7 15IPH11.
2. Run aplay -l — only the NVIDIA HDMI codec is listed; no sofsoundwire card.
3. Run wpctl status — the only sink is the NVIDIA GB207 HDA controller.
4. Run sudo dmesg | grep -iE "sof|soundwire|sdw|snd_soc" — see log below.

No kernel parameters or configuration changes are needed to trigger this; it is
the default state after installation.

Reproduction Rate

All the time — 100%, on every boot since installation. No configuration or user
action has been found that changes the outcome.

Expected behavior

The SoundWire configuration reported by ACPI on this board should be matched to a
machine driver entry that loads a valid topology for the RT1320 speaker amplifier
and the combo jack codec, registering an ALSA card with working internal
speakers, headphone jack and internal microphones.

Failing an exact match, the generic function-topology fallback should generate
unique DAI link names per device rather than colliding on
SDW3-Playback-SimpleJack, so that card registration does not abort.

Impact

Showstopper for all internal audio. Internal speakers, combo jack and internal
microphones are all unavailable. Workarounds are limited to USB or Bluetooth
audio devices, or HDMI output.

Environment

1. Versions
   • Kernel: <uname -r> (Ubuntu 26.04 LTS, package 7.0.0-31-generic)

   • alsa-ucm-conf: 1.2.15.3-1ubuntu1.5
   • PipeWire / WirePlumber: 1.6.2
2. Topology file
   • No single topology file — the driver reports
     Topology file: function topologies (generic fallback) and never reaches a successful topology load.
   • Firmware file: intel/sof-ipc4/ptl/sof-ptl.ri
   • Firmware lib path: intel/sof-ipc4-lib/ptl
3. Platform
   • Lenovo Yoga Pro 7 15IPH11, Intel Core Ultra 7 356H (Panther Lake)
   • Audio controller: sof-audio-pci-intel-ptl 0000:00:1f.3, PCI ID <lspci -nn>
   • BIOS: TNCN32WW

sof-logger output is not included: the DSP boots successfully, but since the
ASoC card never registers there is no meaningful audio activity to trace. I am
happy to provide sof-logger traces, an acpidump, or to test patches on request.
