Kako da na svojoj zvucnoj kartici naredim da prikaze - pusti sound. Tj kako da iz nekog mog formata bacim signal na zvucnu i da se cuje?

pogledao sam to, ali to mi nije potrebno, meni je potbno da na zvucnoj "bacam" zvuk neke amplitude (npr za cujno podrucje od 20Hz do 20KHz, znaci toliko odbiraka u jednoj sekundi, tj 20000 odbiraka promenljive amplitude), naime kako rade svi ostali formati tipa wav,mp3,wma,mod itd.
Code:
Private Declare Function Beep Lib "kernel32" _
(ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

(ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

Ovo radi, ali zvuk ide kao na DOSu - preko zvucnika sa matične a ne preko muzicke kartice. Ja bih hteo da znam funkciju za zvuk preko kartice.
