[Lubuntu] No pulseaudio explains no local sound on LTSP clients?

[John Hupp]

So even though Pulseaudio is installed by default, apparently there are 
configuration questions viz-a-viz it's relationship with Alsa.

Since Edubuntu's LTSP clients play local sound just fine, if you tossed 
me a few critical bones, I might be able to compare the Lubuntu vs. 
Edubuntu configurations and figure out what to change to get local sound 
working with Lubuntu LTSP.

Of course, with LTSP, there might be the added question of whether I 
would need to change the LTSP chroot image -- but one step at a time!
