As a result, headphone jack detection works only after the user manually turns on "HP/Speaker Auto Detect" in alsamixer, which is not obvious on laptops with combo jacks (e.g. Google Link, Alienware). Change the default to follow the headphone pin config: if the pin verb has presence detect enabled (no AC_DEFCFG_MISC_NO_PRESENCE) and the codec supports it (AC_PINCAP_PRES_DETECT), enable HP_ASEL by default. This lets firmware (coreboot, UEFI, etc.) express whether the headphone jack supports insertion detection. Devices with combo jacks can default to auto-detect; devices with fixed/no jack leave it off.
