Re: [Bug 2112330] Re: Internal microphone not working on ASUS VivoBook with Realtek ALC256 (Ubuntu 24.04 + kernel 6.15)
Yes, I'm happy to help test the patched kernel. Please let me know when the
.deb files are ready and I'll install them and report back.
Thanks again for looking into this!
Best regards,
Anas

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.
