Public bug reported: firmware-sof-signed topology ABI 3:29:1 incompatible with kernel 6.17 ABI 3:23:1 — no internal audio on Arrow Lake with CS42L43/CS35L56
Internal laptop speakers do not work on Ubuntu 25.10 (Questing Quokka). The firmware-sof-signed package (2025.05.1-1) ships topology files with ABI version 3:29:1, but the kernel (6.17.0-14-generic) only supports up to ABI 3:23:1. This causes the SOF topology to fail to load, leaving only NVIDIA HDMI audio outputs available. dmesg errors: sof-audio-pci-intel-mtl 0000:80:1f.3: Topology: ABI 3:29:1 Kernel ABI 3:23:1 sof-audio-pci-intel-mtl 0000:80:1f.3: error: can't connect DAI alh-copier.Capture-SmartMic.0 stream Capture-SmartMic sof-audio-pci-intel-mtl 0000:80:1f.3: tplg intel/sof-ace-tplg/sof-arl-cs42l43-l0-cs35l56-l23.tplg component load failed -22 sof-audio-pci-intel-mtl 0000:80:1f.3: error: failed to load DSP topology -22 sof_sdw sof_sdw: error -EINVAL: snd_soc_register_card failed -22 Hardware: Intel Arrow Lake-S, PCI 8086:7f50 (rev 10), Cirrus Logic CS42L43 + CS35L56 over SoundWire. All codec hardware detected and drivers load. NVIDIA HDMI audio (10de:22e9) works. Packages: kernel 6.17.0-14-generic, firmware-sof-signed 2025.05.1-1 Topology: intel/sof-ace-tplg/sof-arl-cs42l43-l0-cs35l56-l23.tplg Firmware: intel/sof-ipc4/arl-s/sof-arl-s.ri v2.13.0.1 (boots fine) Root cause: The topology uses ABI 3.29 constructs (SmartMic widget type 28) that the 6.17 kernel does not support. Either the kernel needs ABI 3.29 support or firmware-sof-signed needs ABI 3.23-compatible topology files.
