I finally remembered that the WAV player I tried used _SNDPLAY.
Something about how it was implemented, or how I modified it,
led to a click at the beginning and end of sound. I get no
such click now.
Re using sound files in a program, is it better to load them
all during initialization and keep them open, or load/use/close?
Although there are 10 files involved, they're all small (20K)
except one (1M). It's for my chess program, so some of them
are used rather often. Even if the total was 2 megs, that's
peanuts for modern computers, right?
