Is there anyway to control volume of PC in Labview?

[test_man]

I want to control sound card volume using Labview. Is there anyway to do that?
Thanks for your help.

Sound Section Capabilities

SO Volume (Windows, Mac OS, Not in Base Package)
Sets the volume of the sound output device. You specify the volume with a 16-bit unsigned integer in left channel and right channel where 0 indicates minimum and 65535 indicates maximum.

Now I'd imagine needing to do more than that

I believe this is what you need.

Thanks for the reply.
This would control music I am playing but does it control volume of the sound card? I want just like we control volume from system tray.

You need to interface to the Multimedia API by using the waveOutSetVolume function. You can also use the function waveOutGetVolume() to read the current volume settings.
