[chuck-users] WvOut: writes soundfile, but always silent

[Spencer Salazar]

Howdy,

An official update (version 1.3.0.2) has been released which should
fix all of the issues identified in this thread. So, the silent audio
files and crashing when calling closeFile() issues should no longer be
a problem. We also fixed the crash bugs Robin reported in a different
thread.

Thanks all for getting to us with these issues and for your patience!

miniAudicle has also been updated (version 0.2.1b) to use this latest
chuck release:
