The three primary failure points are: * Critically Low Speaker Volume: Sound output through the built-in speaker array is barely audible, even when userspace volume sliders are set to 100%. While the host Realtek ALC287 codec initializes, its companion Cirrus Logic CS35L56 smart amplifiers default to an uncalibrated, low-power fallback state ("FIRMWARE_MISSING") because the system lacks their manufacturer-supplied hardware-tuning profiles. * Non-Functional Speaker-Mute Keyboard LED: Pressing the F1 Audio Mute key on the keyboard toggles the stream status within PulseAudio/PipeWire correctly, but the physical amber LED hardware indicator on the keycap fails to illuminate. The software mute state is disconnected from the motherboard's GPIO controller. * Missing/Dead Microphone Array: The system completely fails to register or capture audio via the internal digital microphone array. The default driver stack attempts to locate the DMIC components on a digital sub-link connected directly to the main processor's AMD ACP block, whereas Lenovo routed the microphone hardware channels through the primary Realtek codec pins.

Verify Amp Calibration & Speaker Volume: Play an audio stream at a standard volume level (30–50%). Confirm it produces crisp, loudly scaled audio. 2. Verify Microphone Capture: Open Ubuntu Settings -> Sound -> Input. Confirm that the ghost "Digital Microphone" tied to the AMD ACP is gone, and a functioning Internal Stereo Microphone device is present. Speak or tap on the chassis to confirm that the input visualizer bar responds dynamically to incoming audio data. 3 Verify Mute LED and Mic LED Illumination: Press the physical F1/F4 Mute hotkey. The amber LED light on the keycap must illuminate immediately when muted, and cleanly shut off as soon as the system is unmuted. [ Where problems could occur ] Scope of Regression: Extremely isolated. All changes are heavily guarded behind rigid DMI string check loops inside vendor-specific sub-drivers (AMD ACP matching tables, Realtek HDA quirk lists, and specific sub-hardware ID firmware loading paths). Systems built by other vendors (such as Dell, HP, or ASUS) or other laptop lines will bypass these conditional rules entirely. -- PR: Resolute: https://kernel.ubuntu.com/forgejo/kernel/linux-firmware/pulls/387 Noble: https://kernel.ubuntu.com/forgejo/kernel/linux-firmware/pulls/384 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2156867/+subscriptions
