You can easily check by "core audio.dll" api.

download coreaudio.dll from here

Refernce it in your project and..

than use the following code:

private function getmute() as boolean
    Dim devenum As New MMDeviceEnumerator
    Dim device As MMDevice = devenum.GetDefaultAudioEndpoint(EDataFlow.eRender, ERole.eMultimedia)
    If device.AudioEndpointVolume.Mute = True Then
        Return True
    Else
        Return False
    End If
End Function

hope this works....

(sorry for bad english)
