Try this out.

Edit /etc/X11/gdm/Sessions

Right towards the top you should see this:

 	# initiate sound configs
 	if [ -f /etc/profile.d/ltsp-esound.sh ]
 	        . /etc/profile.d/ltsp-esound.sh

Change this to:

 	# load profile
 	if [ -f /etc/profile ]
 	        . /etc/profile.d

I *think* that will do the trick. Let us know if it works or not.
If it works I should update the icewm packages...
