how many audio jacks do your laptop have ?

/sys/class/sound/hwC1D0/init_pin_configs:
0x12 0x90a60140
0x14 0x90170110
0x15 0x0321101f
0x16 0x40000000
0x18 0x411111f0
0x19 0x411111f0
0x1a 0x411111f0
0x1b 0x411111f0
0x1d 0x40d6832d
0x1e 0x411111f0
0x1f 0x411111f0

/sys/class/sound/hwC1D0/driver_pin_configs:
0x19 0x03a1913d
0x1b 0x03a1113c


seem driver assign sequence number c and d to some of the pin to indicate
support of headset mic and headphone mic

do your laptop specification support headset, headphone or mic if your
laptop has only one jack ?

did the dialog popup ?

I've also tried enabling/disabling "CAPTURE" on the Capture channel at
