Im trying to set the volume level on my pc I took all infomation from these 2 sites Reference 1 and Reference 2 Ive tryed many varations of the following but nothing seems to change the volume level. Ive manually set the volume to 0 in Volume Control, and then called the dll like so DllCall ( "Winmm.dll", "int", "auxSetVolume", "int", 0 , "int", 0x80008000) Then I closed and reopened volume control but the volume is still at zero. What am I doing wrong ? Edit: Id like to point out that neith
