any of those players you mentioned should play it fine so the first thing that occurs to me is that it might be the mp4 itself

have you tried it on another device and confirmed the sound does play?

second thought is that isnt mp4 just a 'container' as in it could have a few different types of audio maybe it has been encoded with a non standard audio format?

if the audio plays through another device id maybe try re-encoding the audio using vlc on a pc

It's not all in the title; please be more precise. Do you mean that all your mp4s won't play the audio or one mp4 in particular? The more information you give, the better the chance that someone can help.

If you have access to a PC then a utility like GSpot or MediaInfo can give you info on the codecs, etc. in a video file.
