[K12OSN] Java applet audio

Has anyone been able to get audio directed to client workstations from 
Java applets? I'm administering an ESL lab based on K12LTSP 6, using ESD 
sound. All other audio apps work fine on the workstations, but anything 
Java-based stubbornly attempts to play through the server.

One of the main Java applets on which the lab depends is the audio 
bulletin board from the Gong Project: 


Interestingly, I can get Java audio redirected to the clients using an 
LTSP configuration of Ubuntu; this distro uses PulseAudio, and with it I 
need to invoke Firefox with 'padsp firefox'. This gets the sound playing 
on the clients, but it's almost too sluggish (long wait for startup) to 
be useful.

I can always dedicate a couple of freestanding machines for use with 
Java stuff, but it would make for a more seamless student experience if 
these apps were available on all lab machines.
