Check your media player. VLC is bloated, but works fine for most people. Mplayer might be a good alternative.
Media Player Classic is the better choice for PC Users.

I hear sound using VLC but not with the default quicktime player on Mac.
It's really not a biggie but maybe for the future releases to make sure the mp4 has a compatible audio codec for both platforms.
..and great job on those cleanups!
