I tried out creating a audio playing applet and it works for me using Ubuntu
10.10 32 bit.

I dont think the 32/64 bit change is a problem. Pulse-java should work fine on
x86 and x86_64. About the only thing different is where the native libraries
are located, but as the stack trace shows, the native libraries are found.

Hm... this is quite interesting. SecurityWrapper loads the libpulse-java.so
library will full privileges. I cant see why it would be denied permission. Do
you have any custom policy files or anything that could deny these permissions?
Can you please confirm that the file
usr/lib/jvm/java-6-openjdk/jre/lib/ext/i386/libpulse-java.so exists and is
readable.

That's quite expected. Oracle's proprietary plugin uses a different
JDK/plugin/mixer, so it should not be affected by these Java problems.

Right, but I dont see this with the default setup. Have you changed any
security settings in Java? Can you possibly retry with a fresh install?

If you can reproduce the problem on new installs as well, then please post the
example. I would like to take a look to see where the problem is.
