I think all that's doing is saying play the sound whenever the items are added. I looked in the BGT manual, what you want is discussed in the get position method under reference > helper layer > object reference > dynamic_menu.

And I am guessing you defined tick earlier in the code which you did not paste here because of brevity.

if i understood correct, you want if go to like this...
you are in start game, and you want if go down, it play sound, if press enter, play sound, and etc.
do this
void setupmenu(bool music=false, bool main=false)
{
m.reset(true);
if (music==true)
m.add_music("menumus.ogg");
if(main==true)
m.set_callback(main_events, "");
else
m.set_callback(cme, "");
m.edge_sound="menuedge.ogg";
m.click_sound="menuclick.ogg";
m.open_sound="menuopen.ogg";
m.enter_sound="menuenter.ogg";
m.speak_letter=true;
//m.letters_autoactivate=true;
m.repeat_items_at_edges=false;
m.enable_first_letter_navigation=true;
m.allow_escape=true;
m.wrap=false;
m.enable_up_and_down=true;
}

At post 1. The best solution to this is using the m_pro.bgt include. It's actually another version of dynamic menu with lots of new features. One of them is what you want. You can asign the tick_sound in your game and you'll have a tick sound when ever the player moves between menu items

no you have to download it and put it in your project dir then include it into your script.

Pelantas find nicklasMCHD in the github, He has a repossetory that all those bgt includes are there, You can download them as a zip file. Well i don't know if you call it repossetory or what, I'm not a professional github user.

Here ya go

Hi,

There's also my enhanced menu include. I crated it by modifying the dynamic menu. One of the things I added was menu sounds.
