Hi there guys,

I'v got the Girls und panzer pachislo but the sound settings in the game menu it self dont do anything. iv to open the doors and use a little button (see Photo's)
i want it to get fixed so i dont have to open it and just can adjust in the menu like it supose to. the button is standart with the machine but i cant figure out how the settings work for it.

I hope someone can help me or got some Idea's about it! would apprieciate it very much!
