[BUG] HP EliteBook X G2i (Panther Lake): No SoundWire machine driver found

[irradiatedcircle]

Hardware / OS

System: HP EliteBook X G2i 14
CPU: Intel Core Ultra X7 358H (Panther Lake)
Audio Device: Intel Corporation Device [8086:e428] (rev 01)
Subsystem: Hewlett-Packard Company Device [103c:8e86]
OS: Ubuntu 26.04
Kernel: 7.2.0-070200rc5-generic

Issue:

Internal speakers are completely dead and WirePlumber falls back to Dummy Output. The headphone jack works because the driver panics and falls back to generic function topologies, but it fails to map the SoundWire machine driver for the onboard smart amps (tas2783 and rt712).

Relevant dmesg Output

Looks identical to the mapping failure happening on the OmniBook X (issue #11027). I have my ACPI DSDT tables ready and attached to this issue. Let me know what other dumps or tests you need to get the quirk mapped for this board.
