• camera(ok)
• audio(ok) --- can play youtube
• microphone(not ok) --- aucat -o file.wav records no sound, can't figure out yet...

followed faq13:

sysctl kern.audio.record=1
rcctl start sndiod

then

# cat > /dev/audio0 < /dev/zero &
[1] 9926
# audioctl play.{bytes,errors}
play.bytes=3312000
play.errors=0
# audioctl play.{bytes,errors}
play.bytes=7065600
play.errors=0
# audioctl play.{bytes,errors}
play.bytes=9379200
play.errors=0
# kill %1
# fg %1
cat > /dev/audio0 < /dev/zero
