How to detect if a sound card exists on a system.

'Note: This has only been tested with VB 3 and VB 4-16, if you convert

' Declare this API
    Declare Function auxGetNumDevs% Lib "MMSYSTEM" ()

' In the appropriate routine:

Dim i As Integer
    i = auxGetNumDevs()

If i > 0 Then ' There is at least one sound card on the system
    MsgBox "A Sound Card has been detected."

Else ' auxGetNumDevs returns a 0 if there is no sound card
    MsgBox "There is no Sound Card on this system."

End If
