Hi people,
I'm trying to get recording from the mic input of my laptop working, but have
not have success so far. I'm using a thinkpad laptop
with an azalia device and a pretty run of the mill headset, attached to
headphone out and microphone in. The headset itself works
fine on other machines and the microphone input and headphone output of the
laptop work fine hardware-wise (i.e. tested with another
operating system). On OpenBSD however, the mic input remains silent. Files
recorded with aucat -o foo.wav remain silent for the
entire recording duration, as if the mic was somehow muted. Below is the
output of mixerctl:
outputs.spkr_source=dac-0:1
outputs.spkr_mute=on
outputs.spkr=125,125
outputs.spkr_eapd=on
outputs.hp_source=dac-0:1
outputs.hp_mute=off
outputs.hp=155,155
outputs.hp_dir=output
outputs.hp_boost=off
outputs.mic_dir=input-vr80
inputs.beep_mute=off
inputs.beep=108
inputs.mix_source=dac-0:1,mic,hp
inputs.mix_dac-0:1=125,125
inputs.mix_mic=215,215
inputs.mix_hp=125,125
record.adc-0:1_source=mic
record.adc-0:1_mute=off
record.adc-0:1=253,253
outputs.hp_sense=plugged
outputs.mic_sense=plugged
outputs.spkr_muters=hp
outputs.master=157,157
outputs.master.mute=off
outputs.master.slaves=spkr,hp
record.volume=255,255
record.volume.mute=off
record.volume.slaves=adc-0:1
As you can see, all recording related devices are at full volume and no device
is muted except for the built-in speakers. Is
recording on azalia devices simply not supported or am I missing something
really obvious here?
