[K12OSN] sound faq for LTSP?

[light being]

I have been asked to get the sound working on a bunch of K12LTSP terminals.

It seems a little confusing though - some daemon on the server will capture 
the sound date and send it to the terminal sound cards, I assume.

What happens to the server sound card?  It just sits there?  Is it usable?  
Does it not even need one?

I was planning to setup the sound card on the server first, assuming it was 
simpler, to learn something, but now that I think of it...

BTW, I had a terminal rebooting problem that is now completely solved, the 
terminals are stable and solid as rocks!   Turning on NFS-swapping did the 
trick.

Thanks!
