VLC: how to choose audio device?

I'm trying to use the VLC player with my web cam.I have the video working, but don't know what to put for the audio device name when I use 'media > open capture device'
Here is a list of /dev
root@Squeeze:~# ls /dev
agpgart hpet net sda2 snd tty18 tty33 tty49 tty7 vcsa
block initctl network_latency sda4 sndstat tty19 tty34 tty5 tty8 vcsa1
bsg input network_throughput sda5 sr0 tty2 tty35 tty50 tty9 vcsa2
bus kmsg null sda6 stderr tty20 tty36 tty51 ttyS0 vcsa3
cdrom log parport0 sda7 stdin tty21 tty37 tty52 ttyS1 vcsa4

I'd like to find the sound device for the built in mike for the web cam as well as the external mike.

Using Debian Squeeze

I don't know if this will help, but here is the choices of sound cards in alsa: attached file. I press F6 to choose the USB, and press Enter, but not sure if that is how to select it.

Thanks for help

Use the 0 Intel choice in alsa mixer which is the Intel. On mine, it- VLC, shows hw:0.0 with the drop down arrow in the sound device in vlc preferences.

$ inxi -A
Audio:     Card: Intel 82801I (ICH9 Family) HD Audio Controller driver: snd_hda_intel Sound: ALSA ver: 1.0.25
with the drop down arrow.
It will not show in /dev (hw:0.0) With my bad eyes, I am not sure if that is hw:0period0 or hw:0comma0 that vlc shows me when the drop down arrow is pressed in sound preferences. So, here is a copy and paste

$ cd /dev
 /dev $ ls

$  cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfc500000 irq 46
 $ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.25.

Thanks. I had to go into alsa and it gave me the choice of mikes to chose from: picked USB Camera. In VLC used hw:1,0 for the web cam mike.
