[BUG] No soundcard detected on LG 16Z90U-H (Intel Panther Lake / RT713 / RT1320)

[vladdubinin]

Hello, I would like to report an audio bring-up issue on an LG laptop with Intel Panther Lake.

System information:

• Laptop: LG Electronics 16Z90U-H.AU87U1 / 16Z90U
• DMI: LG Electronics 16Z90U-H.AU87U1/16Z90U
• BIOS: P1ZK3090 X64 03/06/2026
• SKU: EVO
• Distro: Fedora Linux 44 Workstation
• Kernel: 7.1.1-300.fc44.x86_64

Audio information:

• PCI audio device: Intel Corporation Device [8086:e428]
• PCI subsystem: LG Electronics, Inc. Device [1854:0567]
• Driver: sof-audio-pci-intel-ptl
• SoundWire codecs detected in kernel modules/logs: rt712-sdca, rt1320

Problem:

No sound card is created, so there is no internal speaker output and no ALSA playback device to test.

  Device-1: Intel driver sof-audio-pci-intel-ptl

Firmware/topology note:

Fedora provides the SOF files through alsa-sof-firmware, not a package named sof-firmware. The installed package is:

alsa-sof-firmware-2025.12.2-1.fc44.noarch

/lib/firmware/intel/sof-ipc4/ptl/ contains the requested PTL firmware as a compressed root-level file, and also under community/ and intel-signed/, for example:

/lib/firmware/intel/sof-ipc4/ptl/sof-ptl.ri.xz
/lib/firmware/intel/sof-ipc4/ptl/community/sof-ptl.ri.xz
/lib/firmware/intel/sof-ipc4/ptl/intel-signed/sof-ptl.ri.xz

There are also several PTL topology files installed by alsa-sof-firmware, but I do not see the exact topology requested by the kernel:

intel/sof-ipc4-tplg/sof-ptl-rt713-l3-rt1320-l1-2ch.tplg

Related files I do see include:

/lib/firmware/intel/sof-ipc4-tplg/sof-ptl-rt713-l3-rt1320-l12.tplg.xz
/lib/firmware/intel/sof-ipc4-tplg/sof-ptl-rt713-l2-rt1320-l13.tplg.xz
/lib/firmware/intel/sof-ipc4-tplg/sof-ptl-rt712-l3-rt1320-l2.tplg.xz
/lib/firmware/intel/sof-ipc4-tplg/sof-ptl-rt712-l2-rt1320-l1.tplg.xz

This looks like the machine driver is selecting a topology name that is not present in the installed firmware/topology set, or this LG model needs a different topology mapping/quirk.

Please let me know if there are additional logs or ACPI dumps that would help.

@vladdubinin Could you try #5767?
