I seem to have stumbled nearly blindly into a solution for this problem.
With the knowledge that pulseaudio is not installed by defaulton
Lubuntu, and yet I now have it installed, I can perhaps conclude that it
was installed as a dependency requirement for VLC or some other media
app I was testing.
But is it running in the LTSP client sessions? And relatedly, do I have
to install pulseaudio in the LTSP image, or does a simple installation
on the server machine suffice?
In lxterm on the server, I ran pulseaudio and it responded with a
message like "Daeman already running." Running pulseaudio in lxterm on
the client, it hung without response. An unexpected response. Ctrl-C
got me back to the prompt.
So it was not clear if pulseaudio was running in the client session. I
did a chroot procedure into the LTSP image, then sudo apt-get install
pulseaudio, which responded with a message like "pulseaudio already has
the most current version installed."
Nonetheless I ran the command to update the image. Then rebooted the
server and booted up the client.
LOCAL SOUND NOW WORKS!!
Interestingly, running pulseaudio in lxterm on the client still hangs.
So a why-is-that curiosity question still remains.
And if I were doing a fresh install of LTSP on Lubuntu, I would still be
foggy about exactly what was required to support local sound on the
clients, though I have perhaps enough experience now to poke around and
get it working.

I am copying this discussion that I started in the Lubuntu mail list
over into the LTSP list. The issue is that on Lubuntu 12.04 with
LTSP, the LTSP clients don't play sound locally. Sound plays through
the LTSP server's speakers. But on Edubuntu 12.04 with LTSP, the LTSP
clients play sound locally just fine.

A couple more notes:
I find that Pulseaudio is indeed installed on Lubuntu Precise, so
perhaps the previous post's "We don't use pulseaudio" remark refers
merely to non-usage by Skype, rather than to fundamental configuration
in Lubuntu?
In Edubuntu 12.04, local sound works fine on LTSP clients. So Alsa
and Pulseaudio are configured differently in Edubuntu/Ubuntu than in
Lubuntu?

I'm forking a previous post to a related yet distinct topic.
I hadn't posted anything on the topic yet since I have not tested my
observation more widely, but I seem to find that LTSP clients
connected to a Lubuntu LTSP server do not have local sound. They
output to the server's speakers.
Vaguely I recall that LTSP relies on pulseaudio, so your statement
below could explain the behavior.
If this assessment is correct, anyone know of a relatively easy way
to get local sound working with LTSP on Lubuntu?

We don't use pulseaudio so pavucontrol makes no sense. Skype only
used with alsa reveals the alsa devices in skypes configuration for
audio devices. This works usually fine.

Today I had to use Skype, and I noticed that there's no way to
change the microphone volume. There's no GUI for doing that. So I
googled and, at the Ubuntu forums recommended to use pavucontrol as
a unique pulse audio controller.
Shouldn't we include this app in the distro? I mean, maybe more
people need to control more device's levels and they have no choice.
Or maybe I'm wrong and I'm not using the right tool.
Thanks.
