Winmm.Dll 是可以检测声卡的一般信息的

下面是网上找的 但不知道怎么检测声卡是否有使用

Declare Function Waveoutgetnumdevs Lib"Winmm.Dll"() as Long
Public Const Mb_ok= & H40

Public Function Testcard() As Boolean
Dim Y As long
Dim Find As String Find = “Fied Sound Blaster Card"
Y = Waveoutgetnumdevs()
If Y > 0 Then
Testcard = True
Msgbox "啥啥，我找到你了--声卡!", Mb_ok,Find
Else
Testcard = Falsc
Msgbox "未发现设备",Mb_ok,Find
End if
End Function

Declare Function Waveoutgetdevcaps Lib "Winmm.dll" Alias"Waveoutgetdevcapsa"（ByvaI Udcviceid As Long，Lpcaps As WaveOutcaps， ByvaI Usize As Long） As Long
