I don't, never looked at audio code before, but the above has two changes:

The condition has the '2 *' bit in it, and the body of the if has
+        wwo->dwPlayedTotal = wwo->dwWrittenTotal;
The TRACEs are noops, can be ignored.

So I suggest trying them out individually, to see which one
causes the problem (or maybe they can not be separated). 
Experimentation will tell. :)
