Hardware Details: - Laptop: Huawei MateBook D14 2022 - Audio Codec: Conexant SN6140 (reported as SN6140 Analog under legacy HDA, subsystem ID 0x19e5:0x327e) - OS: Arch Linux (Omarchy) - Kernel: 7.2.3-arch1-3 - Sound Server: PipeWire / WirePlumber What was tested: 1. Standard fallback 'snd-hda-intel' initializes the card in legacy analog mode. It creates a phantom "Internal Microphone" jack port but it stays completely dead (silence). 2. Forcing 'options snd-intel-dspcfg dsp_driver=3' to engage Sound Open Firmware (SOF) breaks the PCH bus entirely: the audio card completely disappears from the system, and the I2C-connected touchpad lock up (stops moving, only clicks respond). 3. Manual pin retasking via 'hdajackretask' on Pin 0x19 (setting it to Internal Mic / Other Digital In) does not route the DMIC stream correctly. 4. The wired headset mic via 3.5mm jack works perfectly under standard legacy mode (dsp_driver=1), but the internal digital mic array remains completely inaccessible. Here is my ALSA information link: https://alsa-project.org/db/?f=2cc12e607be21d152c7f6e955013eff00dbbd432 Could you please assist in creating a correct UCM profile or kernel patch/quirk to map the digital microphone array for this Conexant SN6140 revision on Intel Alder Lake platforms?
