I'm using ld10k1 to accomplish that. I have written the init_live script
   distributed with ld10k1, but unfortunately there is a problem with the
current release. I have attached an updated version that should work.
You have to change the path to lo10k1, if it isn't installed in /usr/bin.

The master volume is called "Master Digital". It also have separate pcm
and front channel inputs, which are needed for the pro-logic decoder.
The front input uses FX 8 and 9, that are unused on SB Live! 5.1, and
"PCM Front" controls the volume.

You will need a customized .asoundrc to use surround output with init_live:

# Output to FX
pcm.fx {
          @args [ FX0 FX1 ]
          @args.FX0 {
                  type integer
		default 0
          }
          @args.FX1 {
                  type integer
		default 1
          }
          type hooks
          slave.pcm {
                  type hw
                  card 0
                  device 0
          }
          hooks.0 {
                  type ctl_elems
                  hook_args [
                          {
                                  name "EMU10K1 PCM Send Volume"
                                  index { @func private_pcm_subdevice }
                                  lock true
                                  value [ 255 255 0 0 255 0 0 0 0 255 0 0 ]
                          }
                          {
                                  name "EMU10K1 PCM Send Routing"
                                  index { @func private_pcm_subdevice }
                                  lock true
                                  value [ $FX0 $FX1 15 15 $FX0 $FX1 15 15
$FX0 $FX1 15 15 ]
                          }
                  ]
          }
}

# Reroute front to FX8,9
pcm.!front {
	type plug
	slave.pcm "fx:8,9"
}
