Take a look at [Java Sound API](http://stackoverflow.com/tags/javasound/info) — Eugene, Jun 19 '13 at 07:26
This is not possible without an audio loopback driver or a sound device that supports it. — Brad, Jun 19 '13 at 12:59

This has been asked many times. The answer is that the feature you want is not supported by Java (in fact, it is hard todo in any environment). This is not unreasonable since some operating systems don't support it. Your options are:

use a cable to connect the PCs output to its input. If you use an analog cable this will introduce some noise.
Use software like soundflower (mac only) to create a virtual cable.
Use JNI to access a low-level API for your system that can do it.
