Question

When I start up my app the main menu comes up and when I click either of the 2 buttons it makes the button sound and then goes to the designated layout. The problem I’m having is that if I go back from the layout to the main screen and try to hit the buttons again it still takes me to the layout but without making the button sound. Any ideas? Thanks for the help.

EDIT: Try this:

if(buttonSound.isPlaying()) {
    buttonSound.stop();
}

try {
    buttonSound.prepare();
} catch (IllegalStateException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

buttonSound.start();
