 Thanks for the reply. My observation for an mp4 conversion (ffmpeg v6) is
 this:

 {{{
   ffmpeg -y -i EAC3.mkv -c:v copy -c:a ac3 "AC3 v6.mp4"

   ffprobe -show_streams "AC3 v6.mp4"

 shows: initial_padding=0 on the audio stream.
 }}}

 ... and it plays correctly in the older player I referred to. I have
 attached the mp4 file.
