Maitha - what are the errors? There are some MATLAB Online limitations that might be related to the audio functions that you are trying to execute.

I mostly guess the following would have been the error.
Error using audioDeviceWriter/validatePropertiesImpl
No audio output device detected
Error in audioDeviceWriter/play
The app audioDelayEffectsExampleApp uses audioDeviceWriter to play the sound to the sound card. It belongs to Audio Toolbox and currently it is not supported in MATLAB Online.
I suggest you using a normal installed MATLAB version.Refer the following site for Installing MATLAB if you already not.
