I hate to say it, but I've had this type of problem with Tux Paint,
Mplayer, and Firefox (when using Flash, e.g. on YouTube), at various
points using Ubuntu.  (Just on a desktop, no LTSP).

Did we determine whether Pulseaudio is being used?  Does disabling it
help?  You could also possibly try to ask SDL to use different sound
drivers.

Do other games (e.g., Vectoroids or Defendguin (a pair of mine) or SuperTux
or Battle for Wesnoth) exhibit the same behavior?  What about non-SDL-based
stuff, like Amarok or other music players, Adobe Flash, etc.?

If they all do, then it's really an issue at a lower-level.  libSDL or
the audio subsystem or drivers.  Developers from those projects would be
better suited to actually fix the issue.

I'd love to figure out a work-around (e.g., ask SDL to use a diff. audio
driver via env. variable), though, so that the bugs can finally get
marked fixed, even if the lower-level stuff doesn't get fixed quickly.
