Public bug reported: I have no audio output (aside from Bluetooth) on my ASUS Zenbook S14 UX5406AA with Intel Core Ultra 9 386H (Panther Lake), running Ubuntu 26.04 LTS Beta with kernel 7.0.0-10-generic.
All the audio hardware appears to enumerate correctly over SoundWire: - cs42l43 codec on link 3 (probed, devid 0x042a43 rev a1) - 4x cs35l56 SmartAmp on links 1+2 (all probed, fw 3.4.4) - rt722 on link 3 - SOF firmware boots successfully (v2.13.0.1) However, when the topology file loads (sof-ptl-cs42l43-agg-l3-cs35l56-l2.tplg), it fails: sof-audio-pci-intel-ptl 0000:00:1f.3: Topology: ABI 3:29:1 Kernel ABI 3:23:1 sof-audio-pci-intel-ptl 0000:00:1f.3: error: can't find BE for DAI alh-copier.Playback-SmartAmp.1 sof-audio-pci-intel-ptl 0000:00:1f.3: tplg sof-ptl-cs42l43-agg-l3-cs35l56-l2.tplg component load failed -22 sof_sdw sof_sdw: probe with driver sof_sdw failed with error -22 cat /proc/asound/cards shows: --- no soundcards --- I'm not sure whether this is caused by the topology ABI mismatch (3:29 vs 3:23) or by the sof_sdw machine driver missing DAI link definitions for this Panther Lake codec configuration. I tried downgrading SOF firmware to v2.13 and v2.12 releases but all available PTL topology files have ABI 3:29:1, so I couldn't test with a matching ABI.
