Describe the bug
The sof_sdw machine driver completely aborts hardware instantiation on the ASUS Zenbook S14 (UX5406AA) due to two intersecting faults:
A phantom RT722 codec broadcast in the ACPI tables, causing the SoundWire master to time out (-110). (Likely requires a zero-endpoint DMI quirk similar to PR Add RTNR library path for MT8195 #5754).
A topology ABI mismatch rejecting the widget routing matrix with a -22 (-EINVAL) component probe error.
To Reproduce
Steps to reproduce the behavior:
Boot the OS with standard sof-firmware installed on this hardware.
Observe the missing audio devices in userspace ("Dummy Output").
Check dmesg for sof_sdw initialization failures.
Reproduction Rate
100% of the time on every boot.
Expected behavior
The kernel should successfully apply a DMI quirk to bypass the ghost RT722 node, parse the topology successfully, and initialize the Cirrus Logic CS42L43 bridge and CS35L56 SmartAmps to expose the hardware to ALSA.
Impact
Showstopper for internal audio. The internal speaker array and built-in microphone do not function.
