Event for autopilot buttons audio

[Voxen]

Hi

Im almost done with my SPADnext bindings.
I still have a little thing I can't.

What event or variable value should I trigger/set to hear the audio of autopilot buttons when pressed, like I can hear them with the mouse (HDG, NAV, ALT, etc).

By only sending events like AP_NAV1_HOLD, the button is pressed but I can't hear the sound of it.

Thanks!
