How do I add generated audio to a silent video?

I have written following code to add generated audio into a silent video. It executes smoothly. But the audio doesn't get added into the "newvideo.avi" file.

videoFReader = vision.VideoFileReader('silent_pgwl1s.avi');
% videoFWriter = vision.VideoFileWriter('newvideo.avi','AudioInputPort',true);
videoFWriter = vision.VideoFileWriter('newvideo.avi','AudioInputPort',true);
for i=1:75
    % videoFrame = step(videoFReader);
    % step(videoFWriter, videoFrame,predgwo);
    videoFrame= step(videoFReader);
    videoFWriter(videoFrame,orgvf) ;
end
release(videoFReader);
release(videoFWriter);
