Programmatically Control the PC audio card volume and sample rate instead of application's volume and sample rate

[DK5445]

Hi all

      Can somebody help me to figure out how I can set the volume and sample rate of the audio device instead of the applications.

     I try to call winmm.dll but I can only set the application's volume and sample rate. 

Thanks and Regards

诸位大神：

谁能教我一个用VI 控制声卡音量和采样率的办法，而不是控制应用程序的音量，我调用winmm.dll也只能配置应用程序的音频信息。

谢谢了。

Hello All,

Is there a solution for this?  Even if the PC volume can be set that would be great.
