Your card already has independent hardware devices.

To make a different device the default device for two different users, put
the following settings in their ~/.asoundrc files:

defaults.pcm.dmix.device 0

defaults.pcm.dmix.device 1

(This is user specific, not X session specific.)

I tried that, that particular suggestion didn't work, but I changed it to 

pcm.!default rear:Live  and 

pcm.!default front:Live

which did work partially.  However, it broke sound in firefox.  It also
messed up some flash programs (links could not be clicked in the flash
program).  Very strange.  I removed the .asoundrc files and the links work
and the sound in firefox.  I must have sound in firefox because this is my
kids computers and they love their flash games.

Also, I was hoping to get the devices X session dependant.  I heard someone
suggest chrooting each X session, copying the dev directory and linking
/dev/dsp to /dev/dsp[x] (whatever number card you want for the given X
session).

Thanks,

John
