Overview

This PR fixes audio volume instability and missing channel boost on the ASUS Zenbook 14 UX3405CA (ACPI Subsystem ID 1043:1A63).

Problem

Previously, SSID 10431A63 matched missing_speaker_id_gpio2 in cs35l41_prop_model_table.
This fallback routine caused:

  1. The right speaker channel to bind with VSPK: 0 (Voltage Switch Boost disabled).
  2. A sudden volume drop (~1 second after starting playback) due to speaker protection power imbalance.
  3. Sub-optimal overall volume gain compared to Windows.

Solution

  1. Added an explicit entry for SSID 10431A63 in cs35l41_config_table specifying internal boost type, 4500mA peak current, and 24uF capacitance.
  2. Mapped 10431A63 to generic_dsd_config.

Tested and confirmed working on ASUS Zenbook 14 UX3405CA running Linux.
