Years ago I ran into similar issues - you might want to look at the short thread API Call to ring system bell/play .WAV Thread #258772 Message #258772 . Probably the most reliable way to play your sound is via an API call such as Anatoliy outlines.

However, when looking through the old threads I found a tip from DraganN which might be worth a try:

* Instead of
?? CHR(7)
* try
WAIT CHR(7) NOWAIT
