I’ve booted into the test kernel (6.14.0-1005-oem) and can confirm that the
internal microphone now works correctly without any manual model override
in alsa-base.conf.

Thanks very much for the patch and support! Let me know if you’d like me to
test anything further or help validate future builds.

Title:
  Internal microphone not working on ASUS VivoBook with Realtek ALC256
  (Ubuntu 24.04 + kernel 6.15)

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  I'm using an ASUS VivoBook (11th Gen Intel i7, Realtek ALC256 audio
  codec). On Ubuntu 24.04.2 LTS, the internal microphone is detected and
  listed correctly in PulseAudio/PipeWire and ALSA, but no input is
  captured. Microphone volume and boost are set to 100%, not muted.
  Input device appears as RUNNING in pactl, but no signal is recorded.

  I tested:
  - Ubuntu 24.04 with default kernel (6.11)
  - Upgraded to mainline kernel 6.15 via `mainline` tool
  - ALSA, PipeWire, PulseAudio all installed and working
  - External USB mic works perfectly
  - BIOS does not expose any audio/microphone control
  - Mic also tested with `pw-record`, `arecord`, `gnome-sound-recorder` — all silent

  ALSA info:
  https://alsa-project.org/db/?f=6d6466ba903b2e08b351046571e0fc54ddd13981

  It seems like a pin configuration or unsupported codec issue with
  ALC256. Please advise if this requires a patch or model-specific
  quirk.

  Thank you.
