求Window 7/10下如何让主板蜂鸣器发声（Beep API无效）？

kevinchan2006

在Windows XP下面，调用下面的API就可以使主板喇叭发出蜂鸣声：
Private Declare Function Beep Lib "kernel32" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

但是在Windows 7/10中无效，查了资料表明，Windows 7/10使用这个API之后，是驱动音箱发声的（不再是电脑主板），如果电脑没有音箱，就无法发声了。

请问各位大神，有没有办法在Windows 7/10上驱动主板喇叭发出蜂鸣声？
谢谢

蜂鸣器那点破音就不要用了。再说现在好多主机都没装蜂鸣器

Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long

Private Declare Function sndPlaySound32 Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszName As String, ByVal uFlags As Long) As Long

Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Private Declare Function Beep Lib "kernel32" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long   

自己测试吧，哪个能用就用哪个
