I have written a program using vb.net and the framework that plays a video, however if the user mutes the sound on a video when they do not have a sound card installed it generates an error.

Can someone tell me how to check a sound card exists before attempting to mute the sound.

Private Declare Function waveOutGetNumDevs Lib "winmm.dll" () As Long
Private Sub cmdCanPlay_Click()
    Dim i As Long
    i = waveOutGetNumDevs()
    If i > 0 Then
        MsgBox "Your system can play sound files.", _
        vbInformation, "Sound Card Test"
    Else
        MsgBox "Your system can not play sound Files.", _
        vbInformation, "Sound Card Test"
    End If
End Sub
