Do you need special name for the external subwoofer jack detect control for
pulseaudio automatically switch from stereo profile to 2.1 profile ?

int snd_hda_jack_add_kctls(struct hda_codec *codec,
   const struct auto_pin_cfg *cfg)
{
const hda_nid_t *p;
int i, err;

...

for (i = 0, p = cfg->line_out_pins; i < cfg->line_outs; i++, p++) {
+     if (cfg->line_outs == 2 && i == 1)
+         err = add_jack_kctl(codec, *p, cfg, "External Subwoofer");
+     else
err = add_jack_kctl(codec, *p, cfg, NULL);
if (err < 0)
return err;
}

> The headset microphone works.
> The headphone, headset microphone and microphone jack detection seems to
work in PulseAudio (showing by plugged or unplugged status).
> However it does not automatically switch the (un)plugged microphone.
> My guess is that it does not know if it should use the headset microphone
or the microphone (instead of the default internal microphone).

switching between the internal microphone and headset microphone?

  Headphone Mic Jack - indicates headphone and mic-in mode share the same
jack,  i e, not two separate jacks. Hardware cannot distinguish between
headphone and a mic.
   Headset Mic Phantom Jack - indicates headset jack where hardware can not
distinguish between headphones and headsets
   Headset Mic Jack - indicates headset jack where hardware can distinguish
between headphones and headsets. There is no use popping up a dialog in
this case, unless we already need to do this for the mic-in mode.

Auto mic need headset mic support jack detection

There are two methods, both methods need to give up the capability of using
headphone and mic

cannot use hint for user to select this feature since user hint is applied
after pin fixup

1) create headset mic jack as slave of headphone jack , this use headphone
jack sense for the jack state of headset mic

        spec->gen.combo_use_only_as_headset = 0;

2) change headphone jack to headset jack, this require add [Element
Headset] to pulseaudio conf files

        spec->gen.headset_and_no_hp = 0;

Method 1 -

Cons - hda-emu cannot emulate this master slave jack ctl and gated/gating
jack ctl

Method 2

Cons - some notebook has

a) headset and headphone jacks

b)r headset and dock headset
