I always thought that I understood the Windows PlaySound() API function:

With the flag SND_ASYNC, the sound is played asynchronously and
PlaySound() returns immediately after beginning the sound.

with the flag SND_SYNC, PlaySound() returns after the sound event
completes.

However I've been testing some code which calls PlaySound() from within
a thread, with SND_SYNC set, and the PlaySound() call returns long
before the sound has finished playing. For a 60 second sound, the
PlaySound() call returns after less than 500 milliseconds. In fact,
it's behaving a lot like it should with SND_ASYNC.

This is happening both on a W2K box with SP4, and XP with SP2. Has
anyone else seen this?
