The headphone jack is not detected on this Huawei Matebook (Conexant SN6140 codec). The BIOS incorrectly marks Pin 0x18 as [N/A], causing the driver to report hp_outs=0 and no "Headphones" output appears. Override the pin configuration for NID 0x18 to set it as a headphone jack, which restores proper detection and audio routing.
