Yes.  You need to add a softvol control.  The following file will give you
one called "Master" and set up dmix which will allow you to play more then
one stream at once. This file assumes your card is card 0. If not change
the "pcm "hw:0,0" and "card 0" lines. Note that dmix is hardset to 48khz
so you will need to change your sample rate in your card settings to match
or else things will sound too slow or too fast.

Here's my /etc/asound.conf.

pcm.dmixer {
     type dmix
        ipc_key 1024
        ipc_key_add_uid false
        ipc_perm 0660
        slave {
                pcm "hw:0,0"
                rate 48000
                format "S32_LE"
                period_time 0
                period_size 1024
                buffer_time 0
                buffer_size 8192
                #was 5120

pcm.softvol {
   type softvol
   slave.pcm "dmixer"
      control {
          name "Master"
          card 0

# change default device:
pcm.!default {
     type plug
     slave.pcm "softvol"
