I suggest you read very carefully the documentation on the wave callback
functions. You must not call any other wave functions (such as
waveOutUnprepareHeader) or any but a select few Win32 functions from within
these callbacks.
I have found it easier to use the window messages (MM_WOM_DONE, etc) rather
than the callback functions, as there are no restrictions on what can be
called from within the window message loop.
