The BIOS of the F+ FLAPTOP r laptop (Realtek ALC897, SSID 1e63:6d9a) declares only pin 0x1b, the headphone output of the 3.5 mm combo jack. Every other external pin is left at 0x411111f0, so the headset mic pin 0x19 is never parsed and no headset mic input exists. The pin is wired on this board - retasking it makes the headset mic record. Reuse ALC897_FIXUP_HP_HSMIC_VERB, which already sets the pin config this machine needs: 0x19 as a headset mic without its own presence detect. Only 0x1b reports jack presence here, so a mic pin with presence detect would leave the driver in auto-mic mode waiting for an event that never arrives. Without the quirk the generic parser retasks the lone headphone pin as an input instead. That surfaces as a "Headphone Mic" input which records only the internal mic bleed, so the headset mic appears present but dead. Tested on ALT Linux, kernel 6.12, by recording a CTIA headset mic on the combo jack with the internal mic as a reference.
