Does it mean that the headset/mic is a mono mic ?

Is the internal mic mono or stereo ?

the functions parse_input() and change_cur_input() in patch_cirrus.c
seem expect ext mic and int mic for auto mic detection

e.g.

	/* check whether the automatic mic switch is available */
	if (spec->num_inputs == 2 &&
	    cfg->inputs[0].type == AUTO_PIN_MIC &&
	    cfg->inputs[1].type == AUTO_PIN_MIC) {

so it won't switch mic automatically when there is one mic pin


	if (spec->cur_adc && spec->cur_adc != spec->adc_nid[idx]) {
		/* stream is running, let's swap the current ADC */

it swap the ADC if the external mic and internal mic are connected to
different ADCs

but there is no mic connected to other ADC

does the vumeters change when you change the sliders of node 0x0d or
0x06 in hda-analyzer ?

pulseaudio just sum the stereo input to mono , and you get silence if
the left/right channel is out of phase

you need to use hda-jack-retask or early patching to change the pin
default of  node 0xe,  0xc or 0x12 default to "ext mic"

either hda-reconfig or early patching  if  node 0x0e, 0x0c 0r 0x12 is ext mic

Only the pincap of node  0xc and 0xd support jack detect , and node
0x0e and 0x12

the last resort is to use hda-verb to check jack detect  of pin 0xd,
0xe, 0xc and 0x12


hda-verb /dev/snd/hwC0D0 0x0d GET_PIN_SENSE 0
