Getting sound to play and stop

I am trying to start and stop playing music in GUI matlab

% --- Executes on button press in Start.
function Start_Callback(hObject, eventdata, handles)
% hObject    handle to Start (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

playersound

% --- Executes on button press in Stop.
function Stop_Callback(hObject, eventdata, handles)
% hObject    handle to Stop (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

stop(player)

I call my function playersound but I do not hear any sound.

function player=playersound
%My Function
[y,Fs]=wavread('Phone_01.wav');
player=audioplayer(y,Fs); 
play(player)

It works if I run the function or use it in the command window but in the GUI it does not. Please bare with me as I am new with GUI but I think it is not calling back properly.

Thank you

It shows that it is playing but I do not hear anything.

This is basically identical to:

Your audioplayer object is going out of scope when playersound() exits. When it goes out of scope, the object is deleted.

You need to save the player object and you need to be able to get to that player object in your stop callback.

Would this affect my ability to hear the music when I press the button because even that is not working.

Thank you

Yes it would.
