No SoundWire machine driver found on HP EliteBook X Flip G2i (Panther Lake, rt712-sdca + tas2783)
System
- Model: HP EliteBook X Flip G2i 14 inch Notebook Next Gen AI PC
- Board: 8E86 (product SKU D4VJ0UA#ABA)
- BIOS: Y90 Ver. 01.01.18 (05/21/2026)
- CPU platform: Intel Panther Lake
- Kernel: 7.2.3-arch1-3 (Arch Linux)
- Audio stack: SOF firmware 2.14.1.1 (sof-firmware 2025.12.2), alsa-ucm-conf 1.2.16.1
Problem
No usable audio output/input. PipeWire/WirePlumber only sees a "Dummy Output" — no real sink or source is created. ALSA does expose raw PCM nodes for headphone jack, HDMI 1-3, jack-in and a microphone device, but WirePlumber can't build real nodes from them because ALSA UCM can't detect a speaker/mic codec — the card's components string is empty (/proc/asound/card0/components doesn't exist), so the generic sof-soundwire UCM profile's regex matching against ${CardComponents} never matches anything.
Kernel log shows the same "no machine driver match" failure reported in #5928 (HP OmniBook X Flip 16-cb0003), with the same rt712-sdca device ID (0x025d:0x0712) but a different board — this looks like it affects multiple new HP "AI PC" Panther Lake models, not just one SKU.
Separately, and possibly related: the TAS2783 speaker amps (link 2, mfg_id 0x0102) are failing to initialize with repeated SoundWire IO timeouts (fw request, wait_event timeout, FW download failed), independent of the missing machine-driver match.
