That can't be right. What's the output of amixer?
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.
Aha! Good catch. I missed that. And now the obvious question is,
"Why?" Why does udev think that that a webcam is a sound card?
Isn't the right solution to this problem to prevent a webcam
from being misidentified as a sound card?
Will be fixed next upload of alsa-base.
There is already a bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=574593
http://svn.debian.org/wsvn/pkg-alsa/?op=rss&rev=2385&sc=1&isdir=1
That doesn't answer why udev thinks webcam is an audio card.
