Hello,

I have a class which I need to create a GUI. I am new to MATLAB and could really use some help.

What I'm planning to do is when a push button is pressed, the audio file plays then stops. I pasted the part of the script below with the audio in it.

% --- Executes on button press in pushbutton3. Reset Button
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton3 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
set(handles.listbox1,'Value',1)
set(handles.popupmenu1,'Value',1)
listbox1_Callback(hObject, eventdata, handles)
load handel;
player = audioplayer(y, Fs);
play(player);
popupmenu1_Callback(hObject, eventdata, handles)

_____________

Thanks!!

Change

play(player)

to

playblocking(player)

Otherwise the function will return after it starts playing, and when it returned it would destroy the local variables including the variable that stores the audio player; that would stop the playing.
