Hardware doesn't make sence.
>Description:
A Deadlock happens on the sound capturing (captureLine.read(...)) after a
second open of the Capture Line.
It looks like a DeadLock in a native part of the java sound library.
>How-To-Repeat:
- start the JavaSoundDemo.jar
- select the "Capture/Payback" tab
- press the "Record" button, recording will start
- press the "Stop" button, recording will stop
- press the "Record" button, recording WILL NOT start
>Fix:
Hopefully a "restart of the sound system" before opening a CaptureLine will
help (if all corresponded threads will be killed).
But the implementation classes are not public.
