I am pretty sure disabling the sound card would be a bad thing, it is heading towards making a virus. If you mean muting the volume, use the waveOutSetVolume:

Public Declare Function waveOutSetVolume Lib "coredll.dll" (ByVal device As IntPtr, ByVal volume As Integer) As Integer

(taken from PInvoke.net)

Where the volume is a bundle of two shorts, which can also be seen as this:

Public Structure volume
    Public left As Short
    Public right As Short
End Structure
Public Declare Function waveOutSetVolume Lib "coredll.dll" (ByVal device As IntPtr, ByVal volume As volume) As Integer

Dim rval As Integer = waveOutSetVolume(0, 0)

Mutes the volume.

For enabling/disabling take a look at this post (in c++)
