How can I interrupt the playback of an audio file that has been initiated using WAVPLAY in MATLAB 7.9 (R2009b)?

I have created a GUI application which starts the playback of an audio file using WAVPLAY. I would like to insert a new button in the GUI that allows the user to pause or stop the audio playback.

There is no function in MATLAB that can pause or stop audio playback once initiated by WAVPLAY. Instead of using WAVPLAY, an alternative is to create an AUDIOPLAYER object. This type of object has methods which allow pausing, resuming and stopping the audio playback. For example:

player = audioplayer(Y, Fs)

% start the playback

play(player);

% pause the playback

pause(player);

% resume the playback

resume(player)

% stop the playback

stop(player)

For further details refer to the AUDIOPLAYER documentation.

See Li Kang's answer below -- the "clear sound" command works, at least for some cases.
