hi i want a wav format song play in the background of my game .after winning or lose the song is stopped

function SnakeGame()
clc
clear
close all

x =randi([10 20],1);%generates random x starting point for snake
y =randi([10 20],1);%generates random y starting point for snake
button =randi([1,4]);% generates random direction to start in for snake
a =randi([1 24],1);%generates random x coordinate for apple
b =randi([1 24],1);%generates random y coordinate for apple
snake=[x,y];%defines the snake for x and y coordinates
snake = [snake ; [snake(1,1)-1 , snake(1,2)] ;[snake(1,1)-2 , snake(1,2)]];
apple=[a b];%defines apple for a and b coordinates

figure('KeyPressFcn',@keyPress);
    function keyPress(~,event)%callback function for movement
        switch event.Character
            case 30  %up
                button = 1;
            case 31   %down

            case 28   %left
                button = 4;
        end
    end

%runs the snake as long as its within the game board

To play audio continuously, you would need the Audio System toolbox, and you would have to periodically queue more samples to output.

sound() always plays the complete sound data passed to it; there is no possibility of stopping it early. To play again, you would have to call sound() again. Caution: if you call sound() while sound() is already playing, you might get both sounds at the same time

audioplayer() can playblocking() which blocks until the given data is played, which would not be good for the flow of your game

audioplayer() can play() without blocking. You can stop() the object to stop early. You cannot play sound continuously with an audioplayer object. However, you can set the StopFcn callback to call play() again -- just watch out that this would be called if you ran stop() on the object. So you might prefer to instead create a timer object that does play() on the audio object. There might end up being some gaps in the sound. There is no way to change the queued sounds for an audioplayer object: if you want to choose between different sounds you need multiple audioplayer objects.

load handel;
p = audioplayer(y, Fs, 'StopFcn', @(varargin) play(varargin{1}) );
play(p)

... eventually ...

set(p, 'StopFcn', []); stop(p);

If you don't clear the stopFcn in this example then stop(p) will indeed trigger the play() again.
