No Sound MacBook Pro MP4
Just picked up a MackBook Pro this afternoon. None of the MP4 video files I have created previously have sound. Downloaded them to the desktop and video plays but no sound. Mute is NOT on.

I have to ask the obvious question because you did not specify... Do you get sound from any application? If yes, then you need to install the necessary CODEC that was used to encode the audio in the MP4 files you have. If NO, well you must solve this first. Check the port where the speakers are plugged into if using external speakers that is.
Yes getting sound from everything except imported video files that work fine on the PC.
Internal speakers only.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Other MP4s work fine the only ones that are givinge me issues are ones previously edited.
The software used to edit the file is where the issue comes from. Any program that creates an audio or video stream for playback has to be encoded with a CODEC. There are dozens, if not hundreds of different CODECs in the wild. The same CODEC must be used to decode the stream during playback. Whatever CODEC was used to encode the file you have MUST be used to DECODE the file. There is really no other option.
Did you try the VLC program? What program did you use to edit the files on the PC?
Yes, VLC is playing correctly - I'm happy with that.
