Thanks for the input but using pulseaudio is not an option.

start such script when user is logging in:

#!/bin/bash

# in order to match a screen-set to a pulseaudio sink :

if [ "$DISPLAY" ]
then
if [ "$DISPLAY" = ":1" ]
then
sleep 3
pacmd "set-default-sink alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set_1.analog-stereo"
pulseaudio -D
fi
if [ "$DISPLAY" = ":2" ]
then
sleep 3
pacmd "set-default-sink alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-stereo"
pulseaudio -D
fi
if [ "$DISPLAY" = ":3" ]
then
sleep 3
pacmd "set-default-sink alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set_2.analog-stereo"
pulseaudio -D
fi
fi

ofcourse edit script with your sound devices and find out where the sound is going to( at which display).
Make sure the user's /home/user/.pulse is empty upon login.
Enjoy
