Hi Maciej, 

There are 3 mixer devices:

/usr/home/jmz % ls /dev/mixer*
/dev/mixer0 /dev/mixer1 /dev/mixer2

I have set the rec device; $mixer =rec mic

Looking again at the output for `cat /dev/sndstat` perhaps this should
be set to rec (pcm2: <USB audio> (rec)) as the webcam is usb peripheral?
I will try both to see. Does this sound correct to you?
