lib and button interaction

[ghettobuilder2027]

Hi,
Here is my loop :
void loop()
{

btn1.loop();
btn2.loop();
btn3.loop();
btn4.loop();
audio.loop();
}

The button pressed are not working well, sometimes they do their job sometimes nothing happens.
I have used the same loop with a vs1503 without any issue
my library for buttons is button2.
Here is my complete source code :

What could I do to solve the problem?

I use four buttons to change volume and change radio stations maybe I need a more suitable way of handling button pressed. Any thoughts?
