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

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.
