Recently I had a similar problem with pulseaudio. everything seemed to
work, but I didn't get any sound. Then I realized pulseaudio was using
null_sink, which throws all sound to the sink. It only uses null_sink
when no other usable sound device is detected, but alsa was working...
Then I saw the problem was that the pulse user (which runs pulseaudio)
didn't have permissions to open /dev/snd/* so I added the following
code to the /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
initialization script, just before running pulseaudio:
# Detect and report a common problem with thin clients
if [ -d /dev/snd ]; then
   chown pulse /dev/snd/*

I don't know if this problem is specific of my setup or it's a real
bug, anyway I wasn't brave enough to file a bug report because I'm
pretty new to LTSP
