Recording from azalia does not work
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? -- Gregor Best [demime 1.01d removed an attachment of type application/pgp-signature]

Same here. My azalia connected mic works under OSX but not under
OpenBSD. Did you ever figure out a solution?

I have a similar problem. I've got a Macbook Air 5.1 running OpenBSD
5.5-stable. The microphone seems to be there, but I'm not able to get it
to record anything (aucat -o produces a silent file). The speakers and
headset work fine. Also, I noticed that Gnome 3 sound settings list no
input devices.

I don't have azalia, so both of us might be missing something obvious :) -- Alexandre

I may be losing my mind... I just rebooted and tried it again and it worked. The mixer settings are the same... looks like this was just some sort of glitch. I'll do some more checking if it stops working again. -- Gregor Best [demime 1.01d removed an attachment of type application/pgp-signature]
