If you have a .wav file i think this will work. First load your file:
[y f]=audioread('yourMusicFile.wav');
Then play audio with:
sound(pl);
Stop sound with:
clear playsnd;

Like Sean answered, try audioplayer:
player = audioplayer(y,f);
play(player);
pause(player);
resume(player);
stop(player);

This doesn't work you say?:
[y f]=audioread('21.mp3');
player = audioplayer(y,f);
play(player);

reema 2014-8-14
no itss not work.. i can;t hear the song even:

i think the handle to the player disappear after the callback and therefore the audioplayer disappear. try:
persient player;
[y f]=audioread('21.mp3');
player = audioplayer(y,f);
play(player);
or this is just a guess but maybe just:
[y f]=audioread('21.mp3');
handles.player = audioplayer(y,f);
play(player);

Joakim Magnusson
Joakim Magnusson 2014-8-14
Doesn't this work with audioplayer? :
stop(player);
What do you mean with profesional tones ?
reema
reema 2014-8-15
i have a project i want to playback the tone when its run ...soo its a project so the tone should be anyy profeesional
reema
reema 2014-8-15

reema
reema 2014-8-15
noo itss nott work with matlab R2013a ..i don't knw about other versions.. its nott workk when we apply this code :
[y, f]=audioread('21.mp3');
player = audioplayer(y,f);
play(player);
then we can't hear the song even...
reema
reema 2014-8-15
and when we use stop(player); the errror show
Undefined function or variable 'player'.
Error in Face_Detection_And_Recognition>pushbutton1_Callback (line 106)
stop(player);

Like i said , you must "save" the handle to the audioplayer. Either by this at the begining of your code:
persient player;
Or by this whey you create the audioplayer:
handle.player = audioplayer (Y, f);

reema 2014-8-16
no sir, when me use this presient code then error show undefine function presient....its not work with matlab r2013a

What happens when you use handle? Without using persient.
reema
reema 2014-8-16
firstly show the error undefine function presient
reema
reema 2014-8-16
its perfectly work with sound's code then why we use audioplayer
reema
reema 2014-8-16
when me use this code your recommended:
[y f]=audioread('21.mp3');
handles.player = audioplayer(y,f);
play(player);
then error show:
Undefined function or variable 'player'.
Error in Face_Detection_And_Recognition>Face_Detection_And_Recognition_OutputFcn (line 100)
play(player);
reema
reema 2014-8-16
and when me use this code also your recommended:
persient player;
[y f]=audioread('21.mp3');
player = audioplayer(y,f);
play(player);
then error show:
Undefined function 'persient' for input arguments of type 'char'.
Error in Face_Detection_And_Recognition>Face_Detection_And_Recognition_OutputFcn (line 96)
persient player;

audioplayer can play without play blocking (so your other processes and continue).

When you play a song with sound, it blocks audioplayer does not so you can have your code running.
Read the example in the doc linked or at:
doc audioplayer
