Bullet proof method to detect if the sound card / microphone is working correctly. (VB.net 2k3)

I need a button in a form, that will detect if the sound card is installed and functioning correctly.

This bid is in reference to a project that will utilize the microphone to record a sound file. (WAV)

The code below works, but not consistantly. From one PC to another, the exception msgnbox will launch.. Even when the sound card / microphone are working correctly.

Thank you.

Declare Auto Function waveOutGetNumDevs Lib "[url removed, login to view]" (ByVal name As String, ByVal hmod As Integer, ByVal flags As Integer) As Integer

Private Sub LinkLabel1_LinkClicked(ByVal sender As [url removed, login to view], ByVal e As [url removed, login to view]) Handles [url removed, login to view]

Dim i As Integer

i = waveOutGetNumDevs(vbNullString, vbNullString, bNullString)

If i = 1 Then

MsgBox("Sound card installed.")

Else

MsgBox("Your sound card / microphone are not working properly." & vbCrLf & vbCrLf & "Please verify you have the proper drivers installed for your hardware.", [url removed, login to view], "Hardware / Driver Error")

[url removed, login to view] = False

Exit Sub
