I cant believe that Im the only one who is familiar with this function. Following skins that contain this:

GjAk_v2.2_AriNe-22
GjAk_v2.2_AriNe-28
GjAk_v2.2_AriNe-33

Open up the zipped skin. You will find ui_android\audio\speedcamoff.wav

This sound is activated AFTER passing speedcam by the line command: skin_off_sound="speedcam_off" in sys.txt as shown in post #3 above

The skin must be chosen and active for it to work. I do not particular like using certain skins and this is why I request this function as a stand alone UX utility.

Best way to explain is please try it out.

@wojpen
