Public bug reported:

Internal speakers do not produce sound on Lunnen LL6FAW-09.

Laptop: Lunnen LL6FAW-09
BIOS/Firmware: APX938_V00.01_T0017ALN2_ms
OS: Ubuntu 26.04 LTS
Kernel: 7.0.0-22-generic

Audio codec: Realtek ALC269VC
Vendor Id: 0x10ec0269
Subsystem Id: 0x2782a210
Driver: snd_hda_intel / snd_hda_codec_alc269

PipeWire/PulseAudio playback indicator moves, active port is analog-
output-speaker, ALSA mixer is unmuted, Master/Speaker/PCM are 100%,
Auto-Mute is disabled.

Bluetooth audio works when manually selecting the Bluetooth sink:
pactl set-default-sink bluez_output.BE_72_86_73_70_99.1
wpctl set-default 80
wpctl set-volume 80 1.0
wpctl set-mute 80 0

So PipeWire/PulseAudio works. The issue appears specific to the built-in
analog audio path / Realtek ALC269VC / internal speaker amplifier
initialization.

Already tested:
- snd-hda-intel model=auto, generic, laptop-amic, alc269-dmic
- HDAJackRetask pin override for pin 0x14: Internal Speaker / Speaker / Line Out
- analog-output-speaker is active
- ALSA mixer is unmuted

Relevant dmesg:
snd_hda_codec_alc269 hdaudioC1D0: autoconfig for ALC269VC: line_outs=1 
(0x14/...) type:speaker
snd_hda_codec_alc269 hdaudioC1D0: speaker_outs=0
snd_hda_codec_alc269 hdaudioC1D0: hp_outs=1 (0x15/...)

ALSA info:
https://alsa-project.org/db/?f=dbbf99561bb948fba0ae642f70aeda2dd9b596a4

This laptop likely needs a Realtek HDA quirk / pin config / GPIO or
amplifier initialization for subsystem id 0x2782a210.
