@Aleksandr Can you run "sudo apport-collect 2126883" after a fresh boot while you are on both kernels (6.8.0-38-generic, 6.8.0-85-generic)?

The audio device is detected (HD-Audio Generic, codec ALC256), and both Capture and Internal Mic controls are visible and unmuted in amixer. However, no sound is recorded in arecord or seen in PulseAudio/PipeWire input levels. Works on 6.8.0-38-generic Broken on 6.8.0-85-generic I've attached ALSA diagnostic files generated with the `alsa-info` tool. **How they were collected:** - `alsa-info-working.txt` → captured while running kernel **6.8.0-38-generic** (internal microphone working) - `alsa-info-broken.txt` → captured while running kernel **6.8.0-85-generic** (internal microphone not working) Both files were generated using: sudo alsa-info --no-upload --output ~/alsa-info-<state>.txt Since Launchpad doesn't let me upload two files, I merged them into one. **Hardware details:** System: ASUS VivoBook X515DAP (M515DA) Codec: Realtek ALC256 Audio driver: snd_hda_intel / snd_hda_codec_realtek **Summary of the issue:** After updating from kernel 6.8.0-38 to 6.8.0-85, the internal microphone stopped recording audio. The device appears in `arecord --list-devices` and in PipeWire, but no signal is captured. All mixer controls (`Capture`, `Internal Mic`, `Mic Boost`) are enabled and unmuted. Booting back into 6.8.0-38 restores full microphone functionality. **Model quirks tested (no effect):** model=asus-zenbook model=asus-mic model=alc256-asus Please compare the two ALSA info logs — likely a pin configuration or initialization change in `snd_hda_codec_realtek` for ALC256 between these kernels.
