The ASUS Zenbook 14 UM3405GA uses a Realtek ALC294 codec with two
Cirrus Logic CS35L41 speaker amplifiers exposed through the CSC3551 ACPI
device. The machine reports the Realtek subsystem ID 1043:19f4.
Without a PCI quirk, the codec falls back to generic pin matching and the
internal speakers remain silent even though PCM playback completes.
Add the UM3405GA subsystem ID and reuse the same ASUS I2C headset-mic
fixup used by the closely related UM3406HA. That fixup configures the
headset microphone pin and chains to CS35L41 I2C speaker-amp binding.
