do the combo headset support CITA or OMPT headset since
alc_determine_headset_type() does not return value for alc662
the role of the combo jack is determined by first mux_pin , this mean
that the "Headset Mic and "Headphone Mic" in second input source control
have no effect
static void alc_update_headset_mode(struct hda_codec *codec)
{
struct alc_spec *spec = codec->spec;
hda_nid_t mux_pin = spec->gen.imux_pins[spec->gen.cur_mux[0]];
hda_nid_t hp_pin = spec->gen.autocfg.hp_pins[0];
int new_headset_mode;
if (!snd_hda_jack_detect(codec, hp_pin))
new_headset_mode = ALC_HEADSET_MODE_UNPLUGGED;
else if (mux_pin == spec->headset_mic_pin)
new_headset_mode = ALC_HEADSET_MODE_HEADSET;
else if (mux_pin == spec->headphone_mic_pin)
new_headset_mode = ALC_HEADSET_MODE_MIC;
else
new_headset_mode = ALC_HEADSET_MODE_HEADPHONE;
