RtApiWasapi::getDeviceInfo: Unable to retrieve device mix format - audio

Question

I am trying to learn how to use Processing, and so am attempting to use the sound library. When running the either of the first two example programs provided at https://processing.org/tutorials/sound/, the IDE responds with this error:
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
terminate called after throwing an instance of 'RtAudioError'
what(): RtApiWasapi::getDeviceInfo: Unable to retrieve device mix format.
Could not run the sketch (Target VM failed to initialize).
For more information, read revisions.txt and Help ? Troubleshooting.
Also, whenever I try to run a sketch using this library, along with that error, windows says
Java(TM) Platform SE binary has stopped working
Windows is collecting more information about the problem. This might take several minutes...
Could you help me to resolve this issue? I am using a windows vista computer.
This is the second example code:
/**
* Processing Sound Library, Example 2
*
* This sketch shows how to use envelopes and oscillators.
* Envelopes describe to course of amplitude over time.
* The Sound library provides an ASR envelope which stands for
* attack, sustain, release.
