* src/java/org/classpath/icedtea/pulseaudio/PulseAudioDataLine.java:
-split open() into createStream(), addStreamListeners() and
connect(), which can be reused when reconnecting the line for
synchronization
-added recconectForSynchronization()
-made some changes to stop()/start() in order to send
START/STOP events both when corking and in case of underflow
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioMixer.java:
-changes to synchronize()
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioSourceDataLine.java:
-changed connectLine to take the masterStream as a
parameter in case we want to synchronize the Line
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioClip.java:
-changed connectLine to take the masterStream as a
parameter in case we want to synchronize the Line
