Re : Sound with Minim no longer works

Download the Oracle official jdk and replace the processing java directory with it this will fix the sound problem. But If you export your application as a linux app then to make it work you will have to install the official Oracle jdk and jre to your system.

You could do something like this:
1) download the files

2) In the same directory where the files are  execute this commands
export JDKfile="jdk-7u15-linux-i586.tar.gz"
export JREfile="jre-7u15-linux-i586.tar.gz"
export JDK="jdk1.7.0_15"
export JRE="jre1.7.0_15"
export INSTDIR="/usr/lib/jvm"

sudo tar -xvzf $JDKfile -C $INSTDIR
sudo tar -xvzf $JREfile -C $INSTDIR

# Updating
sudo update-alternatives --install "/usr/bin/java" "java" "$INSTDIR/$JRE/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "$INSTDIR/$JDK/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "$INSTDIR/$JRE/bin/javaws" 1
sudo update-alternatives --set java $INSTDIR/$JRE/bin/java
sudo update-alternatives --set javac $INSTDIR/$JDK/bin/javac
sudo update-alternatives --set javaws $INSTDIR/$JRE/bin/javaws
