The udev system recoognized a usb webcam as an audio device
(snd-usb-audio) and it becomes soundcard 0 in ALSA's card devices.

alsamixer by default uses soundcard 0. See alsamixer(1). Webcams
don't have a mixer device.

In /usr/share/doc/alsa-base/README.Debian.gz is described how to set
the priorities of sound devices. To check how much sound devices the
system provides just

$ cat /proc/asound/cards
