Well you'll have to properly configure alsa dmix for that.

It may not work for you (though I think it'll work perfect):

a) Install the proper sound library (it will replace the old one):

sudo apt-get install libesd-alsa0

b) Create /etc/asound.conf:

#/etc/asound.conf

pcm.card0 {
type hw
card 0
}

pcm.!default {
type plug
slave.pcm "dmixer"
}

pcm.dmixer {
type dmix
ipc_key 1025
slave {
        pcm             "hw:0,0"
        period_time     0
        period_size     2048 #1024
        buffer_size     32768 #4096
        #periods        128
        rate            48000 #44100
        }
bindings {
        0 0
        1 1
        }
}

#done

c) Now modify /etc/esound/esd.conf to make it look like that:

# /etc/esound/esd.conf

[esd] auto_spawn=1 spawn_options=-terminate -nobeeps -as 2 -d default
spawn_wait_ms=100
# default options are used in spawned and non-spawned mode
default_options=
#done

d) Now You need to change the sound server to alsa:

gstreamer-properties

and change from OSS to ALSA

e) Restart the computer
