I don't see how that card doesn't exist:

theophile at farmer:/mnt/sdd$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: default [USB Sound Device        ], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0



theophile at farmer:/mnt/sdd$ cat /etc/asound.conf
pcm.!default {
	type hw
	card 1
	device 0	
}


I am noticing that when I run alsamixer, I get this error:
alsamixer: function snd_ctl_open failed for default: No such file or directory

However, it runs when I pass it the '-c 1' flag. Also my other
programs continue to play sound just fine, including AC3 passthrough.
In XBMC, my passthrough device is set explicitly to plughw:1,0 and it
plays fine.
