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)
