Not really sure what you mean by "I have a question regarding closing 
the pulseaudio sinks/source." (namely the "closing" bit). Do you mean 
when you are done and want to exit your application? Or do you just mean 
"stop it from outputting sound"?

If the latter, I think mute is better. Suspend is when the devices have 
been asked to be suspended so that another application can use the audio 
hardware (or on a timeout so that pulse does not sit there hogging the 

e.g. you can run an application that wants direct access to sound h/w via:

shell> $ pasuspender myapp

And it will suspend pulse's access to the device for the duration of the 
applications lifetime.

While I don't know how the Java Ports thing works at all, I'd suspect 
you just want to mute it.
