If you are developing a game in VB or an application that plays sounds, you probably want to check that a sound card actually exists. There is an API function that does this, and returns the number of sound cards installed in the system. Therefore, a return value of zero means that no devices are present or that an error occurred. This is an example:

Private Declare Function waveOutGetNumDevs Lib "winmm.dll" () As Long

If waveOutGetNumDevs() >= 1 Then
    MsgBox "Your system supports a sound card."
Else
    MsgBox "Your system can't play sounds."
End If
