Problems with Audio.au3?

[Damein]

I am attempting to use this but I can't get any of it to work for some reason :/

Here is what I am trying:

#include <Audio.au3>

_SoundSetMasterVolume(50)

HotKeySet("{g}", "GetVolume")

While 1
    Sleep(10)
WEnd

Func GetVolume()
    $vol = _SoundGetMasterVolume()
    MsgBox(0, "Test", $vol)
EndFunc

Which should result in a Msgbox saying 50, but it quits before it even reaches the while, the Set command closes the script.

I have the included file in the same folder as the script I am using, but still nothing.

Suggestions? Thanks.

Do you have the Audio.au3 udf?

[Damein]

Yes, I do.

I have the included file in the same folder as the script I am using, but still nothing.

I stated that there

#include <Audio.au3> = #include 'Audio.au3'
