Do you have an entry like this in your ~/.asoundrc:

  ctl.mixer0 {
      type hw
      card 0        # this should probably be card 1 in your case
  }

?

One unexpected bonus that I got from setting up dmix was that mp3
playing no longer skips when I switch workspaces in my window manager.

If you want to trick a pointy-haired boss into letting you write software in
Lisp, you could try telling him it's XML.
