Assigning sound card to specific X display

[Ken M. <ke...@th...>]

I'm running a dual-head setup using Debian unstable + the x.org packages
from Ubuntu.  I have two sound cards, and I'd like to assign each of
them
to a specific X display.  How can I do this?

The first sound card is /dev/dsp and the second is /dev/dsp1.  I want
display :0 to use /dev/dsp and display :1 to use /dev/dsp1.

I've tried the instructions available at
http://howtos.linux.com/howtos/XFree-Local-multi-user-HOWTO/automation_multy_snd-cards.shtml
but I haven't been able to get them to work with gdm/Gnome.

Thanks,

Ken
