Try with 'aplay -L' and the output should show you which one of the two
is the default. also 'leafpad /var/lib/alsa/asound.state' can show you
what is being used by what in your alsa sound setup at that time.
Leafpad is a text editor, use whichever you're familiar with.
I'm in a similar situation as you regarding soundcards and also with
HDMI support. This is my .asoundrc file;-
========================================
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
pcm.primary {
type hw
card 1
device 0
}
=============================================================
Although these are for sound cards, they might be useful for you?

Are you a member of your local LUG? [Linux User Group]. If so you could
take the webcam along to one of their meetings and get their advice and
support re getting the mic working with it.

Have you checked out the support pages for your webcam supplier? You
may find someone else using linux with that webcam, and see what their
solution was?
