<p class=MsoNormal><span style='color:#1F497D'>Just to clarify, directsound.pas
(or similar units floating on the net) should give you interfaces to the
Dsound.dll. this is what you need to do things like below.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:#1F497D'>I’ve
never used interfaces in Windows before and I’ve got no idea how to do this, so
I’m wondering if someone would like to whip up a Delphi function for me.
I don’t think it would take more than 5 or 10 minutes. I searched the
internet extensively and C++ code exists but nothing for Delphi.<o:p></o:p></span></p>
