The Gigabyte BRIX BXBT-2707 is a mini-PC with Realtek ALC283 HDA, exposing a single headset jack.
However, the default pin config information only suggests that one pin is connected: a HP out jack (pin 0x21, default config 0x04211010).
The microphone input is behind pin 0x19, which has default config 0x411111f0 (i.e. unused), so it does not show up in userspace, and no microphone input is possible via the headset.
Override the pin config so that the headset mic can be used.
The overwritten value looks like the jack-detectable. Is it really so? Many headset jacks don't give the jack detection in the mic pin but relies on the headphone pin jack detection or use vendor-specific way.
thanks,
Takashi
