Here is my audio device and mixer settings if you would like to compare
with the ones you try with:
OpenBSD 5.8 GENERIC.MP#1062 i386
azalia0 at pci0 dev 27 function 0 "Intel 82801GB HD Audio" rev 0x02: msi
azalia0: codecs: Realtek ALC269
audio0 at azalia0
$ mixerctl -av
inputs.dac-0:1=192,192
inputs.dac-2:3=192,192
record.adc-0:1_mute=off [ off on ]
record.adc-0:1=125,125
record.adc-2:3_mute=off [ off on ]
record.adc-2:3=125,125
inputs.mix_source=mic2,beep { mic2 beep }
inputs.mix_mic2=0,0
inputs.mix_beep=120,120
inputs.mix2_source=dac-0:1,mix { dac-0:1 mix }
inputs.mix3_source=dac-2:3,mix { dac-2:3 mix }
outputs.spkr_source=mix3 [ mix2 mix3 ]
outputs.spkr_mute=off [ off on ]
outputs.spkr_eapd=on [ off on ]
outputs.hp_source=mix2 [ mix2 mix3 ]
outputs.hp_mute=off [ off on ]
outputs.hp_boost=off [ off on ]
outputs.hp_eapd=on [ off on ]
outputs.mic2_source=mix2 [ mix2 mix3 ]
outputs.mic2_mute=on [ off on ]
inputs.mic2=85,85
outputs.mic2_dir=input-vr80 [ none output input input-vr0 input-vr50
input-vr80 input-vr100 ]
record.adc-2:3_source=mic [ mic2 beep mic mix ]
record.adc-0:1_source=mic2,beep,mix { mic2 beep mix }
outputs.hp_sense=plugged [ unplugged plugged ]
outputs.mic2_sense=plugged [ unplugged plugged ]
outputs.spkr_muters=mic2 { hp mic2 }
outputs.master=255,255
outputs.master.mute=off [ off on ]
outputs.master.slaves=dac-0:1,dac-2:3,spkr,hp { dac-0:1 dac-2:3 spkr hp mic2 }
record.volume=125,125
record.volume.mute=off [ off on ]
record.volume.slaves=adc-0:1,adc-2:3 { adc-0:1 adc-2:3 mic2 }
I would as well appreciate if somebody could tip which set of options
would define internal and then external microphone selection.
