[PTL] MSI Prestige 13 AI+ A3MG: Missing RT713/RT1320 SOF topology — audio fixed by building upstream topology #11404

Summary

On my MSI Prestige 13 AI+ A3MG-020 with Intel Panther Lake, a fresh Fedora 45 installation had no working audio.

ALSA reported --- no soundcards --- and PipeWire only showed "Dummy Output".

I successfully restored audio by compiling sof-ptl-rt713-l3-rt1320-l1.tplg from the upstream SOF source and installing the compiled topology manually.

System information

• Laptop: MSI Prestige 13 AI+ A3MG-020
• DMI product: Prestige13AIA3MG
• DMI board: MS-13Q4
• Distribution: Fedora 45
• Kernel: 7.2.15-300.fc45.x86_64
• SOF firmware package: alsa-sof-firmware-2026.09.2-1.fc45.noarch
• Audio driver: sof-audio-pci-intel-ptl
• SoundWire topology: RT713 on link 3, RT1320 on link 1

Original kernel errors

sof-audio-pci-intel-ptl 0000:00:1f.3:
SOF firmware and/or topology file not found.

Firmware file:
intel/sof-ipc4/ptl/sof-ptl.ri

Topology file:
intel/sof-ipc4-tplg/sof-ptl-rt713-l3-rt1320-l1.tplg

error: sof_probe_work failed err: -2

Before the fix:

$ cat /proc/asound/cards
--- no soundcards ---

The kernel logs also contained SoundWire transfer timeouts.

Working solution

Cloned upstream SOF:

git clone --depth 1 \
  https://github.com/thesofproject/sof.git \
  ~/sof-audio-src

Source commit:

80b14b070b1e0c89df89b117c94b347866cc8d67

Built the missing topology:

cmake -S ~/sof-audio-src/tools \
  -B ~/sof-audio-build \
  -DCMAKE_BUILD_TYPE=Release

cmake --build ~/sof-audio-build \
  --target topology2_prod_sof-ptl-rt713-l3-rt1320-l1

Installed the resulting file:

sudo install -m 644 \
  ~/sof-audio-build/topology/topology2/production/sof-ptl-rt713-l3-rt1320-l1.tplg \
  /usr/lib/firmware/intel/sof-ipc4-tplg/

I had previously tried a symlink from the packaged -l1-2ch topology but removed it before compiling and installing the upstream topology.

Result

Audio now works.

ALSA detects the soundcard:

0 [sofsoundwire   ]: sof-soundwire - sof-soundwire
                     Micro_StarInternationalCo.Ltd.-Prestige13AIA3MG-REV1.0-MS_13Q4

Possible packaging issue

The kernel expects:

sof-ptl-rt713-l3-rt1320-l1.tplg

The published firmware file lists include:

sof-ptl-rt713-l3-rt1320-l1-2ch.tplg

However, the exact topology requested by the kernel can be built successfully from the upstream SOF source and restores audio on this hardware.

The required topology was introduced in:

#10760

It appears that the corresponding compiled topology may be missing from the distributed firmware package.

Could the maintainers confirm whether the non-2ch topology needs to be added to the firmware distribution, or whether another packaging or kernel-side fix is intended?

I am happy to test an updated firmware package or provide additional logs.

Thanks for your work on SOF!
