[BUG] Infinix INBOOK X2 SLIM (XL23): No internal speaker audio (Intel SST + Everest ES8326)

[Basithmgm]

Describe the bug
I am experiencing a hardware routing issue on my Infinix INBOOK X2 SLIM laptop running BigLinux/Manjaro (Arch-based). The internal speakers are completely silent, though the audio hardware is partially recognized.

The system utilizes the Intel Tiger Lake-LP Smart Sound Technology Audio Controller paired with an Everest ES8326 codec. Applying options snd_soc_sof_es8336 quirk=16 successfully registers the card in ALSA and PipeWire routes to analog-output-speaker, but direct ALSA playback (speaker-test -Dhw:1,0) remains completely silent. The internal amplifier appears to be powered down or misrouted.

Hardware Details

• Laptop Model: Infinix INBOOK X2 SLIM
• Audio DSP (Intel): PCI\VEN_8086&DEV_A0C8&SUBSYS_1A312782
• Audio Codec (Everest): ACPI\ESSX8326 (Hardware ID: ACPI\VEN_ESSX&DEV_8326&SUBSYS_27821A31)

To Reproduce

1. Boot standard Linux kernel (6.x).
2. Codec is not fully initialized without quirks.
3. Apply quirk=16 to snd_soc_sof_es8336.
4. Card registers as sof-essx8336.
5. Run speaker-test -Dhw:1,0 -c2 -r48000 -f S16_LE.
6. Result: Total silence (no errors thrown by ALSA, but no physical audio).

Expected behavior
Internal speaker amplifier should power on and output audio via the correct GPIO pin.

• Attached is my alsa-info.txt generated via alsa-info.sh.
• Attached is a dump of my dmesg logs.

Additional context
I am willing to compile test kernels or test specific GPIO pin quirks if a developer can provide the correct routing map for this specific Subsystem ID (1A312782).
