Fix crash in dsound test

[Robert Reif]

How did this fail in windows.  Since it doesn't crash with wine,
wine is doing something wrong.  Lets try to figure out what is wrong
and correct wine to have the same behavior as windows or at least
notify someone that something is wrong.

Is anyone working on getting direct sound into the windows port
of our regression tests?
