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: Click here to copy the following block 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
