I have observed the same behavior on XP. I noticed that each time a sound is "played" though the msvad device it writes a new file called (stream_XX.wav ) where XX is a sequential number. Only the first file written (stream_0.wav , related to the first sound played through the device) is a valid wav file. all other files that it writes are short files that do not have valid wav audio.
