The "Allow WAV Files to Play" menu option sets a
switch used by the OnAssertPlayWaveFile method;
this method is used to preventplaying Wave sound 
files. (This could be due to lack of Audio 
hardware, or other reasons such as a need to
avoid degrading system performance.)

(Note: Assert methods normally are used to abort
all further processing of an action, while the
Handle Methods modify the processing. These
two methods can each be overridden in code by
direct assignment for Assert types and virtual
overriding for Handle types.)
