A few hints here.

I made a ~/.asoundrc according to the referenced FAQ and find two default devices.

peter@dalton:~$ cat .asoundrc
pcm.!default {
    type hw
    card 2
}
ctl.!default {
    type hw
    card 2
}

peter@dalton:~$ cat /proc/sound/cards
cat: /proc/sound/cards: No such file or directory
peter@dalton:~$ cat /proc/asound/cards
 0 [I82801BAICH2   ]: ICH - Intel 82801BA-ICH2
                      Intel 82801BA-ICH2 with AD1885 at irq 17
 1 [NX6000         ]: USB-Audio - MicrosoftB. LifeCam NX-6000
                      Microsoft MicrosoftB. LifeCam NX-6000 at usb-0000:01:0e.2-
3, high speed
 2 [default        ]: USB-Audio - C-Media USB Headphone Set
                      C-Media USB Headphone Set   at usb-0000:00:1f.2-1, full speed
 3 [default_1      ]: USB-Audio - C-Media USB Audio Device
                      C-Media USB Audio Device    at usb-0000:01:0e.1-1, full speed

More than one default device makes no sense.  Not surprisingly, 
default_1 never produces sound.  So I'm thinking of editing 
/etc/modprobe.d/sound.  There is no default here.  Is the syntax 
of this file documented?  What is the second token on each line?  
"snd-trident" in the wiki for example.  Where can these names be 
found in my system?

Thanks for any ideas,           ... Peter E.
