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:


That doesn't answer why udev thinks webcam is an audio card.
