It's about public multiseat computer.That's one computer(ubuntu) with several 
users.
Each screen or display or seat has an usb soundcard.Every user always logs in 
on the same seat/display.No problem there.
So let's say that a person logs in on screen1(seat1) ,mutes the sound.
A next person logs in at same screen1(seat1) with same username/passwd(these 
are public computers), but founds no sound(sound is muted by last person 
before him), so usualy than i get a phone call about the no sound and have to 
tell to the person to unmute the sound.
So I have to make sure that the sound volume gets unmuted again at login.
So I am thinking to write a script with:
set-sink-volume 0 55000
to be called with gdm postlogin default.
But as there are for example six soundcards, I cannot determine the default 
sink for the users (so i could set the script per user),i have to put all the 
sinks outputs set-sink-volume at login:
set-sink-volume 0 55000
set-sink-volume 1 55000
set-sink-volume 2 55000
set-sink-volume 3 55000
and so on..
This works ok because the default sinks changing sometimes also:
when one usb-soundcards fails or did not wake up in time, the sinks order is 
changing, so I have to re-assign the correct sinks to the correct 
screen/user.(i have also a script for this however).

Last quick note about ubuntu 9.10 and pulseaudio:only one or two usb 
soundcards are detected , still due to the module-udev-detect bug.
