下图是Windows Media Player的声卡选择界面
用AU3可以实现吗？如果可以，代码应该怎么写？

贴上代码吧        可能更容易理解

#include <ButtonConstants.au3>
#include <ComboConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
$Form1 = GUICreate("Form1", 640, 480)
$Input1 = GUICtrlCreateInput(@WindowsDir & "\media\tada.wav", 20, 20, 300, 20)
$Button1 = GUICtrlCreateButton("选择MP3文件", 340, 20, 100, 20)
$Button2 = GUICtrlCreateButton("开始播放", 460, 20, 60, 20)
$Button3 = GUICtrlCreateButton("停止播放", 540, 20, 60, 20)
$Label1 = GUICtrlCreateLabel("声卡选择", 20, 60, 100, 20)
$Combo1 = GUICtrlCreateCombo("", 100, 60, 400, 20, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))
GUISetState(@SW_SHOW)

While 1
        $nMsg = GUIGetMsg()
        Switch $nMsg
                Case $GUI_EVENT_CLOSE
                        Exit
                Case $Button1
                        $File=FileOpenDialog("选择MP3文件", "", "MP3文件(*.mp3)")
                        If @error Then
                        MsgBox(4096,"","没有选择文件!")
                        Else
                        GUICtrlSetData($Input1,$File)
                        EndIf
                Case $Button2
                        SoundPlay(GUICtrlRead($Input1))
                Case $Button3
                        SoundPlay("")
        EndSwitch
WEnd
