alsa-project/alsa-lib issue #500 was opened from nicolas2019alcubo:
Laptop: Acer Aspire AL16-31P
CPU: Intel Alder Lake
Audio codec: Realtek ALC269VC
Audio controller: HDA Intel PCH
Problem:
Internal speakers produce no sound on Linux. Audio system appears functional but output is silent.
Tested distributions:
- Fedora 43 (kernel 6.17.1)
- Ubuntu 25.10
- EndeavourOS (Arch-based)
Observed behavior:
- Speakers detected as "Built-in Audio"
- Audio plays (no errors), but no sound is heard
- Headphones and HDMI output work (if tested, confirm)
- pactl shows sink in SUSPENDED or IDLE state
- alsamixer shows normal levels
Diagnostics:
aplay -l shows:
card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog
Manual test:
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
→ no sound output
Attempted fixes:
- Disabled Auto-Mute Mode
- Forced analog-stereo profile
- Installed alsa-sof-firmware
- Tested multiple kernels and distros
Conclusion:
Likely missing support or initialization sequence for internal speaker amplifier (smart amp).
