Hi Marcel.

Which Linux distro are you using?

If it is a distro that has pulseaudio installed, Ubuntu, Fedora, etc, when 
opening alsamixer on the command line, all you will see is/are the control/s 
for pulseaudio. Open alsamixer as below, and you should see all the controls 
for card0, and card1.

alsamixer -D hw:0
The above should show sliders for your actual soundcard.
alsamixer -D hw:1
The above should show any sliders for the webcam.

Nigel.
