[K12OSN] server-terminal sound, NASD sound modules..?

[light being]

I'm having some trouble installing the correct sound modules, sound servers, 
etc.

at the moment the terminal says "module not found" at boot time...

LSPCI gave me the following for the sound card, indicating an AU8820 chip:

00:10.0 Class 0401: 12eb:0001 (rev 02)

it is listed in /etc/audiolist, however seems commented out.  I un-commented 
it, guessed a module name, but it didnt work.

/etc/audiolist --------------------------
#Aureal Semiconductor
12EB:0001	AU8820		#AU8820 Vortex Digital Audio Processor
------------------------------

the server has some ltsp-esound packages installed - i didnt find any 
"ltsp-sound" packages however, that this website indicates here, installed 
or in the repositories - shouldnt it be in the repository?

http://www.ltsp.org/ltsp-4.1.html.

follows a relevant section of the lts.conf file
