According to msdn
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmfunc_9uxw.asp):

"pszSound - A string that specifies the sound to play.
If this parameter is NULL, any currently playing
waveform sound is stopped."

You so nicely researched and described this bug. It
would be pity if this information is lost :-)

If nobody takes it now, could you submit the
information to Bugzilla?
