Ubuntu Multimedia :: Java Applet No Sound In Maverick

I recently upgraded an ASUS netbook through a series of about 4 or so upgrades ending at Maverick (10.10). Sound in Java applets worked fine before that, but I've been trying for about a week now to get it working again.

Here is what I have tried so far:
Removed Sun Java and plugin, and installed Openjdk and icedtea
Removed Openjdk and icedtea, and installed Sun Java and plugin
Verified through aboutlugins that FireFox plugin matched installed Java plugin
Tried using padsp and aoss wrappers

Along the way I have also tried other suggestions I have found through Google for configuring sound and setting file permissions, but nothing works. No matter what I do, sound keeps working everywhere except in Java applets.

Here are some observations along the way.

Sound has worked everywhere I try except in Java applets. It works with Flash.

Java applets work fine except for sound. Java console indicates that sound files are being received and passed to applets.

My Java executable is located at /usr/lib/jvm/java-6-sun/jre/bin/java. I have tried renaming it "java.real" and creating a shell script that wraps it with padsp or aoss. When I do that Java works, but Java applets fail to start. The Java console does not start up, so the wrappers appear to prevent applets from starting.

I am trying to run applets at [url]. They work fine for me on a 64-bit 10.04 system and a 32-bit 10.04 system.
