Having problems with quickly closing a macro

[AshesOfHegemony]

Thank you very much!
This one works flawlessly:

This should work.
 
Code:
 

Code:

Copy      Help

// script "BF6 spacebar.cs"
/*/ ifRunning end; /*/
script.setup(trayIcon: true, sleepExit: true, exitKey: KKey.MediaStop);

opt.key.KeySpeed = 15;
opt.key.NoBlockInput = true;
opt.key.NoModOff = true;

while (true)
{
    keys.send("Space");
}

My next and final question is; how do i get the sound.speak("Toggle Off"); to play after the macro is toggled off in this code?
 

Code:

Copy      Help

/*/ ifRunning end; /*/
script.setup(trayIcon: true, sleepExit: true, exitKey: KKey.MediaStop);

opt.key.KeySpeed = 15;
opt.key.NoBlockInput = true;
opt.key.NoModOff = true;

while (true)
{
    keys.send("Space");
}
sound.speak("Toggle Off");

Im getting a compilation error at sound.speak();

BF6 Spacebar2.cs(12,1): warning CS0162: Unreachable code detected

The sound effect is not being read before the script closes.
