You have been subscribed to a public bug: 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.
