webcam and audio capture

Hi,

I have a Logitech C270 webcam and I was trying to get webrtc working 
(Firefox Hello). Sound (output) works just fine all the time.

Video capture is being recognized and works, but not audio capture (the 
microphone in the webcam).

The video capture device is /dev/video0 and when testing at 
test.webrtc.org, Firefox asks nicely if I would like to share the 
/dev/video0 device. But the audio device is skipped and doesn't work. In 
FF Hello, video is fine, but the microphone on my side isn't working. I 
can hear and see the people on the other side. But they can see me, but 
cannot hear me.

I have encountered similar problems before with uTox. But in uTox it 
worked after editing a config file (in ~/.alsoftrc pointing the audio 
capture from /dev/dsp (default?) to /dev/dsp4).

The big question is, if it is possible in FreeBSD to always point the 
audio capture to /dev/dsp4, instead of /dev/dsp which seems to be the 
default?

Regards,
Marco
