no audio showing with loaded video in avidemux

[Jan Gruuthuse]

Audio is showing up in mediainfo and plays in VLC

• Most likely this is a  MPEG TS file and does not contain PAT/PTM so brute force is used to detect the tracks. Brute force is not very good at detecting audio
• Use mkvmerge to convert it to a mkv (it's very fast, no quality loss at all)
  the resulting mkv can be opened without troubles

source: No audio tracks showing up (but audio plays in VLC)

Pass video through mkvtoolnix, then loading the newly saved .mkv has avidemux detecting the audio track.
